David Montague de Burgh Kenworthy, 11th Baron Strabolgi (pronounced "Strabogie") (1 November 1914 – 24 December 2010), was a Labour Party peer.
Strabolgi was educated at Gresham's School, Holt, and the Chelsea School of Art.
The title of Baron Strabolgi was created in 1318 for the tenth Earl of Atholl. The barony twice went into long periods of abeyance, during which no claim to hold it could be established, the second of these lasting for over three hundred years.
The second period of abeyance was terminated in 1916 in favour of Cuthbert Kenworthy, the grandfather of the 11th Baron Strabolgi, who succeeded Joseph Kenworthy, 10th Baron Strabolgi, in 1953.
Strabolgi died on 24 December 2010, at the age of 96. He was succeeded in the barony by his nephew, Andrew Kenworthy (born 1967), who became the 12th Baron Strabolgi.
