Wriothesley Russell, 3rd Duke of Bedford (25 May 1708 – 23 October 1732) was an English nobleman and peer.

He was the son of Wriothesley Russell, 2nd Duke of Bedford.

[1][2] Russell married his sister's stepdaughter, Lady Anne Egerton, daughter of Scroop Egerton, 1st Duke of Bridgwater, on 22 April 1725.

Russell courted Egerton, trying to get Sarah Churchill, Queen Anne's famous favourite, as a go-between, for political reasons, as he has opposed Walpole.

He was buried on 14 December 1732 in the 'Bedford Chapel' at St. Michael's Church, Chenies, Buckinghamshire, and his titles passed to his brother, John Russell, 4th Duke of Bedford.
