John S. Gibson Jr. was an American politician, whose career spanned many decades and two states. A member of the Democratic Party from San Pedro, Gibson served on the Los Angeles City Council for the 15th district from 1951 and 1981, and did two lengthy stints as its president. Earlier in his life, Gibson's tenure as Mayor of Geneseo, Kansas made him the youngest elected mayor in the nation at the time.

Los Angeles's 15th City Council district is one of the fifteen districts in the Los Angeles City Council. It is currently represented by Democrat Tim McOsker since 2022, after previous member Joe Buscaino retired to run for mayor that year.
