[1][2] [3] The club was founded as Ballinamore in January 1889 in McGauran’s Railway Hotel.

Unusually for a County Leitrim club, they have always fielded teams in both hurling and Gaelic football.

Local schoolteacher Seán O'Heslin was a driving force behind the club in its early years; he died in 1942; Sean O’Heslin Memorial Park opened in 1952 and the club was renamed Ballinamore Seán O'Heslin's in his honour in 1953.

[4][5][6][7] O'Heslin's also reached the final of the Connacht Senior Club Football Championship on four occasions — 1968, 1973, 1986 and 1990 — losing each time.
