Sir Thomas Butler, 1st Baronet

Sir Thomas Butler, 1st Baronet (died 1642) was an Irish nobleman, the illegitimate son of Sir Edmund Butler of Cloughgrenan and grandson of James Butler, 9th Earl of Ormond.

He was High Sheriff of Carlow for 1612 and 1622. He was created a baronet of Cloughgrenan (a townland near Carlow town) in 1628 by King Charles I. His father had three other legitimate sons; Pierce, James and Theobald. The two elder sons (Sir Thomas's half brothers) were executed by their own uncle Thomas Butler, 10th Earl of Ormond at Thurles during their rebellion in 1596. The third son, Theobald, was created Viscount Butler of Tulleophelim.

This title died with the first bearer. The Cloughgrenan line survives to the present day through the illegitimate line of the baronets.
