Roger Mary Sweetman (18 August 1874 – 20 May 1954) was an Irish Sinn Féin politician and barrister.

[5] An amateur tennis player, he won the 1905 East of Ireland championship,[6] and in 1902 reached the final of the Irish Open men's doubles and lost to Sydney Howard Smith in the first round of the Wimbledon singles.

[7] When John declined on age grounds to stand in the 1918 UK general election in Wexford North, Roger stood instead and unseated Thomas Esmonde of the Irish Parliamentary Party.

[9] In November 1920, breaking ranks with Sinn Féin, Sweetman wrote to the press calling for a truce and peace negotiations in the Irish War of Independence, and criticising Irish Republican Army actions, in particular the assassinations on Bloody Sunday.

[11] Two days later he announced his resignation as Teachta Dála because of his "radical disagreement with the majority ... on a vital matter of policy".
