William Jerome Lampley (November 9, 1876 – January 7, 1944) was a provincial politician from Alberta, Canada.

He served as a member of the Legislative Assembly of Alberta from 1935 to 1940 sitting with the governing Social Credit caucus.

He won a hotly contested race on the third count over three other candidates including incumbent UFA MLA William Bailey.

Elimination of the Conservative candidate and Bailey exhausted many votes as back-up preferences were not marked by many voters.

He contested a straight fight against Independent candidate Eld Martin, who ran for the Conservative-Liberal Party Unity League.
