Patrick Chrestien Gordon Walker, Baron Gordon-Walker, was a British Labour Party politician. He was a Member of Parliament for nearly 30 years and twice a cabinet minister. He lost his Smethwick parliamentary seat at the 1964 general election in a bitterly-racial campaign conducted in the wake of local factory closures.

Smethwick was a parliamentary constituency, centred on the town of Smethwick in Staffordshire. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first past the post voting system. The constituency was created for the 1918 general election, and abolished for the February 1974 general election.
