FINA was founded on 19 July 1908 in the Manchester Hotel in London, UK at the end of the 1908 Summer Olympics by the Belgian, British, Danish, Finnish, French, German, Hungarian and Swedish Swimming Federations.

- Africa (52): African Swimming Confederation (CANA)
- Americas (45): Swimming Union of the Americas (ASUA)
- Asia (45): Asia Swimming Federation (AASF)
- Europe (52): European Swimming League (LEN)
- Oceania (15): Oceania Swimming Association (OSA)
Note: The number following each continental name is the number of FINA members which fall into the given geographical area. It is not necessarily the number of members in the continental association.
The FINA membership meets every four years, usually coinciding with the World Championships. There are two types of normal or "ordinary" congress: General and Technical. FINA's highest authority is the General Congress. Any technical issues concerning FINA's five aquatic disciplines are decided by the Technical Congress. Each Congress has two voting members from each Member federation, plus the following non-voting members: the 22 members of the Bureau, the Honorary Life President, and all Honorary Members. The Technical Congress has the following additional non-voting members: all members from the respective Technical Committees.  "Extraordinary" Congress are also called from time to time, to deal with a specific topic or area of concern (e.g. an Extraordinary Congress was held with the 2009 World Championships to review the Masters swimming rules; there was a General Congress at the 2009 Worlds ). All Congress meetings are chaired by FINA's president. 
Between Congress meetings of the entire membership, a smaller 22-member representative board, called the FINA Bureau, meets to act in a timely manner on items which cannot wait until the entire body can forthgather. It is the Bureau that elects the FINA Executive Officers. 
Various committees and commission also help with the oversight of individual disciplines (e.g. the Technical Open Water Swimming Committee helps with open water), or topic-related issues (e.g. the FINA Doping Panel). 
Each presidential term is four years, beginning and concluding with the year following the Summer Olympics (i.e., 2018-2021 is the current term).
