Kathleen Anne Browne (1 October 1876 – 1943) was an Irish politician, farmer, writer, historian and archaeologist.
She joined Sinn Féin in 1912 and the Irish Volunteers in 1914 and flew a tricolour from her family home, Rathronan Castle, during the Easter Rising. She was arrested and imprisoned in Kilmainham and Mountjoy prisons. She took the pro-treaty side during the civil war, joining Cumann na nGaedheal.
She was elected to Seanad Éireann of the Irish Free State as a Cumann na nGaedheal member, at a by-election on 20 June 1929. The by-election was caused by the death of Alice Stopford Green. She was re-elected for 3 years in 1931 and was re-elected for 9 years in 1934. She joined the Army Comrades Association in 1933. She served until 29 May 1936 when the Free State Seanad was abolished.
