David Hay Petrie (16 July 1895 – 30 July 1948) was a Scottish actor noted for playing eccentric characters, among them Quilp in The Old Curiosity Shop (1934), the McLaggen in The Ghost Goes West (1935) and Uncle Pumblechook in Great Expectations (1946).

[2] He went to Harris Academy[3] and later attended St Andrew's University, where he first discovered the stage.

[4] After the war, he studied with Rosina Filippi, joining the Old Vic Company appearing as "Starveling" in A Midsummer Night's Dream in 1920.

In 1924 Albert de Courville brought Hay Petrie into vaudeville with The Looking Glass, in which he sang "Oh Shakespeare you're the best of all but you can't fill the fourteen shilling stall".

He was never more at home than when he was playing parts from the classical theatre, and for many he was the Shakespearean Clown of the early 1920s.
