William Sharpe (September 22, 1887 – November 24, 1964) 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 Social Credit caucus in government.

No candidate received majority of the votes in the first count in the 1935 Grande Prairie contest.

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

On the third count Sharpe received a majority of votes still in play, maintaining his lead over the Liberal candidate's vote tally.
