Thomas Lawlor (died 29 October 1945) was an Irish Labour Party politician and trade union official. In 1925 the Labour Party identified high taxation as a government weakness and decided to contest the Dublin South and Dublin North by-elections. Lawlor, as general secretary of the Irish Municipal Employees' Trade Union was the candidate in Dublin South, with Denis Cullen of the Irish Bakers Union running in Dublin North. Neither of them were elected.
