Robert Heron Rastall FGS (November 8, 1871, Turnerdale Hall near Whitby, North Yorkshire – February 3, 1950)[1] was a British geologist and petrologist.
During his teaching career, he served for some years as the president of the University of Cambridge's Catholic Association.
In 1916 Rastall began assisting Henry Woodward in editing the Geological Magazine and became in 1919 the editor-in-chief.
Some time around the beginning of WW II, Rastall retired from the University of Cambridge to live in his old home in the village of Ruswarp near Whitby.
In retirement, he did research, in collaboration with John Edwin Hemingway (1906–1997), on Yorkshire's Jurassic rocks.
