David Grayden (né Ives; 25 May 1924 – 9 June 2003) was an Australian politician who was a member of the Legislative Assembly of Western Australia from 1950 to 1953, representing the seat of Nedlands.
Grayden spent part of his early childhood in the United Kingdom, but eventually returned to Perth, where he attended Wesley College.
During World War II, Grayden enlisted in the Australian Army, serving in the Middle East and New Guinea.
At the 1950 state election, he failed to gain official endorsement, but won the seat of Nedlands as an "independent Liberal" candidate.
He worked as a high school teacher until his retirement in 1984, and spent the rest of his life on the New South Wales Central Coast.
