James Lumley (c. 1706 – 14 March 1766) was an English Member of Parliament and landowner.
Lumley was made a Groom of the Bedchamber to the Prince of Wales in 1728, and the following year was elected to Parliament for Chichester, succeeding his brother Charles.
He did not stand for re-election in 1734, instead moving to the King's Household as one of the commissioners of the office of Master of the Horse.
He died "heavily in debt", and left his Durham estates to his nephew Richard Lumley-Saunderson, 4th Earl of Scarbrough and his Sussex estates to his nephew George Montagu-Dunk, 2nd Earl of Halifax.
