The Butt Baronetcy, of Westminster in the County of London, was a title in the Baronetage of the United Kingdom. It was created on 25 July 1929 for Alfred Butt, who represented Balham and Tooting in the House of Commons as a Unionist between 1922 and 1936. The title became extinct on the death of his son, the second Baronet, in 1999.
