Hougang or Aukang is a planning area and mature residential town located in the North-East Region of Singapore. The town is the most populous in the region, being home to 247,528 residents as of 2018.  Hougang planning area is bordered by Sengkang to the north, Geylang and Serangoon to the south, Bedok to the southeast, Toa Payoh to the southwest, Paya Lebar to the east, Ang Mo Kio to the west and Bishan to the southwest.
Hougang is the pinyin spelling of Aū-káng, a Hokkien and Teochew name meaning " river's end", as Hougang is located upstream or at the back of Sungei Serangoon. In the past, the name connoted the area stretching from the fifth milestone junction of Upper Serangoon Road and Upper Paya Lebar Road/Boundary Road to the seventh and a half milestone junction of Upper Serangoon Road and Punggol Road. The area just beyond the seventh milestone along Punggol Road was formerly considered part of Punggol but is now within Hougang Town and that section of Punggol Road is now Hougang Avenue 8, with Punggol Road starting further north. 
Pig farming was carried out in Punggol, including the area of Punggol that is now part of Hougang Town. The last of these pig farmers were relocated by the late-1990s to flats built in Hougang. Today, Hougang is an HDB new town with over 40,000 housing units interspersed with pockets of private residential areas.
There was also a fishing port at the end of Upper Serangoon Road beyond the seventh milestone.
At Hougang Street 21, there was a well that is still identified as the tua jia kha (大井跤) well structure. This well identified the Teochew village of tua jia kha which means the "foot of a big well". In the past, the village was a popular place for food, street wayangs, itinerant Chinese medicine men and story tellers spinning yarns.
The development of Hougang commenced in 1977 with the construction of Tampines Way. Further construction work was subsequently completed in Neighbourhoods 1 – 3 by 1983, and later Neighbourhoods 4 – 7 by 1992. Neighbourhood 8 is the town centre of Hougang and construction was completed in 1994. Neighbourhood 9 is the most recent with a completion date in 2000.
In 2015, a project named Hougang Capeview, a Build-To-Order project at Upper Serangoon Road, became the first public housing project to receive the CONQUAS Star, an accolade administered by the Building and Construction Authority. Hougang Capeview, which comprises 781 residential units in six blocks at Upper Serangoon Road, received a Construction Quality Assessment System (CONQUAS) score of more than 95, above the national average of 88.2. The CONQUAS score is BCA's measure of construction quality across Singapore.

The depot is constructed fully underground and provides maintenance, stabling and operational facilities for the Circle Line. It is located in Hougang, along Upper Paya Lebar Road, and is accessible via Kim Chuan Road.

Most of Hougang's commercial activity is centred on a few shopping malls such as Hougang Mall, Kang Kar Mall, Heartland Mall, Upper Serangoon Shopping Centre and Hougang 1 (Formerly known as Hougang Point, and opened in End 1999).
Similar to most other residential towns in Singapore, Hougang was designed to be a partially self-sufficient with enough amenities to minimize the number of residents commuting to the Central Area. Facilities include Hougang Sports Hall, an indoor sports complex operated by Sport Singapore which runs ClubFITT membership and sports programmes, Hougang stadium home to S.League club Hougang United, an aquatics centre, a number of parks such as Punggol Park, along with many wet markets and hawker centres.

The Hougang Central Bus Interchange serves Hougang Town with a range of bus services going to other parts of the island. It is located in Hougang Central, near Hougang Mall and it has an underground link to Hougang MRT station. This bus interchange was officially opened on 17 February 1995 by former cabinet minister Goh Chee Wee, who was then Senior Minister of State for Communications, Trade and Industry to serve all buses around the Hougang Area. Its sister bus interchange, Hougang South Bus Interchange (that is near to Kovan MRT station) ceased operations in 2004 and was converted to Kovan Hub.
Two even older bus terminals operated in Hougang before the construction of the Hougang Central and Hougang South Bus Interchanges. One was at the end of Upper Serangoon Road in Kangkar Village, which was replaced by Hougang Central, while the other was at the sixth and a half milestone of Upper Serangoon Road, which was replaced by Hougang South. 
A distinctive feature of Hougang lies in the large semi-circular balconies which occur in many Housing and Development Board public housing flats in the area. This feature is not as prevalent in public housing outside Hougang. The latest addition of new Condominium will be Florence Residences in 2019.
The political representation of Hougang was split into four different constituencies as of the 2020 elections, three of which were Group Representation Constituencies (GRC) ( Aljunied, Ang Mo Kio, and Marine Parade), and one Single Member Constituency (SMC) bearing the same name, the Hougang Single Member Constituency. Currently, Aljunied and Hougang wards are managed by the opposition Workers' Party (WP), while Ang Mo Kio and Marine Parade are managed by the ruling People's Action Party (PAP). Previously, Hougang was administered by five now-defunct wards ( Jalan Kayu, Paya Lebar, Punggol, Serangoon Gardens and Upper Serangoon), before it redistricted into GRCs, notably Cheng San GRC (also defunct since 2001).
The area covering Hougang Avenues 2, 5, 7 and a small portion of Hougang Central, falls under the namesake Hougang SMC, where it was carved out from Punggol ward ahead of the 1988 elections. The first Member of Parliament (MP) of the ward was PAP's Tang Guan Seng, until it had been captured by former WP secretary-general Low Thia Khiang in 1991. Low left the ward to contest (and later elect himself in) Aljunied GRC ahead of the 2011 elections, and was replaced by Yaw Shin Leong, another WP candidate who previously contested Ang Mo Kio GRC in the 2006 elections.  Yaw remained as an MP until his expulsion from the party's CEC and resigned his seat in February 2012 over an extramarital affair. Png Eng Huat, a candidate whose part of the WP team contested East Coast GRC in the 2011 elections, had since represented this ward after winning his by-election in May 2012 until he stepped down ahead of the 2020 election. Dennis Tan, who previously contested Fengshan SMC in the 2015 elections (now part of East Coast GRC) and become a Non-constituency Member of Parliament (NCMP), has replaced outgoing Png following the election.
The area covering south of Hougang Avenues 6, 8, 10, as well as Punggol Park, Defu Industrial Park and the subregion of Kovan, falls under Aljunied GRC. The western portions of Hougang, previously being Serangoon Gardens division, were split into two divisions with Jalan Kayu in the Ang Mo Kio GRC and Serangoon in the Aljunied GRC. The area was previously belong to the short-lived Thomson GRC in 1991.
The GRC was not contested in 2001 with the WP being disqualified due to incomplete applications, but in the 2006 elections, the WP were able to pose a strong challenge for this ward, with the members consist of WP's chairwoman Sylvia Lim and former members Goh Meng Seng and James Gomez. 
The GRC was managed by the PAP which members include Cynthia Phua and George Yeo, until it became the first opposition held GRC since the creation of the GRC in Singapore after the 2011 Singaporean general election being taken over by Low Thia Khiang's WP team. The WP continued to hold the GRC in the 2015 and 2020 Singaporean general elections with Leon Perera and Gerald Giam replacing Low and Chen Show Mao.
The north-western portions of Hougang (Avenues 4, 8 and 9, and Street 91), which includes Hougang Stadium and Regentville Condo, falls under the Ang Mo Kio-Hougang division of the Ang Mo Kio GRC. Its MP is Darryl David, who replaces former MP Yeo Guat Kwang after the 2015 elections. Prior to the 2011 elections, the ward was a part of Aljunied GRC (under the name of Aljunied-Hougang), where Yeo was then the MP.
The northern portions of Hougang (north of Avenues 6, 8 and Street 51) also falls under the Ang Mo Kio-Hougang division, part of Ang Mo Kio GRC. It previously belonged to Pasir Ris-Punggol GRC (under the name of Punggol South) until it was carved out in 2015. After the 2020 elections, the portion was merged with the Ang Mo Kio-Hougang division.
The western portions of Hougang, previously being Serangoon Gardens division, were split into two divisions with Jalan Kayu in the Ang Mo Kio GRC and Serangoon in the Aljunied GRC.
The southernmost portion of Hougang, Tai Seng, was under the Geylang Serai division of Marine Parade GRC, where Mohd Fahmi Aliman represented the ward. Marine Parade was also contested by WP during the 2015 and 2020 elections.
The area has a total of nine primary schools, eight secondary schools and one junior college, Anderson Serangoon Junior College (ASRJC). ASRJC was formed after the merger of Anderson Junior College and Serangoon Junior College in 2019.
