John Marshall (1888–1952) was a Scottish sculptor active in the early 20th century.
He is noted for doing much of his architectural work in-situ, on the face of the buildings.
He is thought to be descended from John Marshall, marble cutter on Leith Walk who had been a teacher to Thomas Campbell.
He worked in partnership with architects such as Sir Robert Lorimer and Sir John James Burnet and executed works designed by fellow sculptors such as Phyllis Bone, Benno Schotz, Pilkington Jackson, Alexander Carrick and Hew Lorimer.
He is known to have sculpted the gravestone for William Marshall, his own son, in Drum Brae Cemetery in 1949.
