Gerry O'Sullivan (10 April 1936 – 5 August 1994) was an Irish Labour Party politician from Cork.^[1] He was a long-serving member of Cork City Council, and was Lord Mayor of Cork from 1986 to 1987.

O'Sullivan was elected to Dáil Éireann at the 1989 general election as a Labour Party Teachta Dála (TD) for Cork North-Central having topped the poll.^[2] He was re-elected at the 1992 general election, receiving 10,008 first preference votes, again topping the poll.^[1]

In January 1993, after the formation of a Fianna Fáil–Labour coalition government, he was appointed as Minister of State at the Department of the Marine (with special responsibility for Port Development Safety at sea and Inland Fisheries).^[3]

He died in office in August 1994 following a short illness.^{[citation needed]}

The by-election for his seat was held on 10 November 1994, and was won by Kathleen Lynch of Democratic Left.

In 1996 the Port of Cork commissioned a new 30m, 176 ton tug and pilot vessel which was christened the M.T. Gerry O'Sullivan in his honour. The boat is usually moored in either Cobh or Ringaskiddy.^[4]
