Brian Mullins (27 September 1954 – 30 September 2022) was an Irish Gaelic football manager and player. He played football with his local club St Vincent's and was a senior member of the Dublin county team from 1974 until 1985. Mullins later served as manager of both Dublin and Derry. He was regarded as one of Dublin's greatest-ever players. He was a nephew of Bill Casey, who played for Kerry in the 1930s and 1940s.

Mullins was born in Dublin in 1954. He received his primary and secondary education in Dublin before later attending Thomond College in Limerick. Here Mullins completed a Bachelor of Arts in physical education and Irish.

Mullins subsequently returned to Dublin where he secured a teaching job in Greendale Community School in Kilbarrack on the north side of the city. Here he taught his degree subjects as well history and geography. In 1980 he took eighteen months leave of absence from Greendale to complete a Master of Arts in athletics administration at New York University.

When Mullins returned from the United States he resumed his teaching post at Greendale and stayed there until 1991. That year he was appointed Head Teacher of Carndonagh Community School in Inishowen, County Donegal, Ireland.

Mullins returned to Dublin in 2000 to take up his role as UCD Director of Sport.

In May 2020, the Irish Independent named Mullins at number seven in its "Top 20 footballers in Ireland over the past 50 years".

His son, Nathan, holds an Ulster Senior Football Championship medal from 2018.
