Alexander de Stavenby (or Alexander of Stainsby; died 26 December 1238) was a medieval Bishop of Coventry and Lichfield. Alexander was probably a native of Stainsby, Lincolnshire, and had two brothers, William and Gilbert, who held land there. He may have studied under Stephen Langton, later Archbishop of Canterbury, as Langton was from a village less than 10 miles away. Alexander taught theology at Toulouse before his appointment to the episcopate. He may have been a teacher of Dominic, the founder of the Dominican Order, at Toulouse. He also taught at Bologna and was named a chamber clerk for Pope Honorius III. Alexander was nominated as bishop about 13 April 1224, and consecrated on 14 April 1224.
