Purley Albert Baker (1858—1924) was an ordained Methodist minister who strongly opposed any consumption of alcoholic beverages and was superintendent of the Ohio Anti-Saloon League.

Purley Baker was born in Liberty Township, Jackson County, Ohio, on April 10, 1858.

He attended school in Xenia, read law with a judge in Circleville, and entered the ministry at age 25.

He raised large sums of money to create a major information campaign, an important component of which was to demonize the producers of alcoholic beverages.

He announced his resignation as general superintendent of the League on March 8, 1924, for reasons of ill health.
