Livingston Parish ( French: Paroisse de Livingston) is a parish located in the U.S. state of Louisiana. Livingston Parish is known as one of the six Florida Parishes, a region of the State of Louisiana that was bought from Spanish Florida and created the state of Louisiana as it is known today.
It has become widely accepted that the name Livingston is an eponym honoring Edward Livingston, a prominent American and Louisianan, a jurist and statesman who assisted in the drafting of the Louisiana Civil Code of 1825. 
Livingston Parish is part of the Baton Rouge, LA Metropolitan Statistical Area. As of the 2010 census, the population was 128,026.  Its parish seat is located in the City of Livingston.  Livingston Parish is also part of the 6th Congressional District for the State of Louisiana.
Livingston Parish was created by the state legislature in 1832 from part of St. Helena Parish. The historical parish seats were Van Buren (1832–35), Springfield (1835–72), Port Vincent (1872–81), and Centerville (1881–1941). Livingston became the seat of government in 1941.

Livingston Parish is a Council-President parish governed by a Home Rule Charter and enforced by a Parish Council and Parish President. The Parish President is the head of the executive branch of government, and the Parish Council comprises the legislative branch. 
Livingston Parish is divided into nine council districts. The borders of each district are drawn so as to even out the population in each district.
At the end of 2014, the construction of a new Livingston Parish Courthouse was completed, with the ribbon-cutting scheduled for mid-February 2015. The new facility contains over 100,000 square feet; it replaces an antiquated complex dating back more than seventy years. 
In its early history, Livingston Parish was “ Solid South” Democratic, although it demonstrated Piney Woods voting behavior in 1928 when it was Herbert Hoover’s best parish in Louisiana. Like other parishes in the Baton Rouge metropolitan area, Livingston remained loyal to Harry S. Truman in 1948 and to Adlai Stevenson II in 1956 when Louisiana’s electoral votes went to Strom Thurmond and Dwight D. Eisenhower respectively. Barry Goldwater became the first Republican to win the parish in 1964, and in recent years, Livingston Parish has been one of the most Republican parishes in Louisiana, and one of the most Republican county-equivalents in the nation. It has gone Republican in every presidential election since 1984. In the 2004 election, George W. Bush received 33,976 votes, or 77% of the parish’s total, more than three times the 9,895 votes (22%) his opponent, John Kerry, received.  The Republicans fared better still in the 2008 election, in which John McCain received 43,269 votes (85% of the total) to just 6,681 votes (13%) for Democrat Barack Obama.
The Livingston Parish Public Schools operates all public schools in the parish.
