The Reverend Lucius Doolittle (23 May 1800 – 18 May 1862) was a Church of England priest.

After receiving a B.A. and honorary M.A. from the University of Vermont, Doolittle founded Bishop's College School in 1836 (as Lennoxville Classical School with Cambridge-Graduate Edward Chapman) and co-founded Bishop's University in 1843 in Quebec, Canada.

Doolittle also acted as the rector of Sherbrooke and the borough of Lennoxville. Bishop's College School is Canada's fifth-oldest functioning private school.[citation needed]
