Thomas Cullen (1939 – 5 October 2020) was an Irish Gaelic footballer.
At club level he had some success with Edenderry and was a two-time Leinster Championship winner with the Offaly senior football team.
He began his inter-county career as a dual player with the Offaly minor teams that contested provincial finals in both hurling and Gaelic football in 1957.
Cullen played a role in the Offaly breakthrough, claiming back-to-back Leinster Championships in the 1960 championship and 1961 competition before losing out to Down in the 1961 All-Ireland final.
At club level, Cullen won an Offaly County Championship with Edenderry while still a minor, while he also played a role in the club's rise to the senior ranks of Offaly hurling as they captured the junior championship in 1962 and the intermediate championship in 1963.
