Stony Plain (named Stonyplain until 1909) was a provincial electoral district in Alberta, Canada, between 1905 and 2019.

The riding in its original boundaries stretched from the west Edmonton city limits to the British Columbia border, but over time it was significantly reduced in size.

It was renamed Stony Plain for the 1909 Alberta general election, retaining this name until its abolition.

The area continued to be represented in the Legislative Assembly until the 2019 election, when new riding borders took effect.

The first election in 1905 saw a three-way battle which was handily won by Liberal candidate John McPherson, who was reelected in 1909.

He was defeated by Conservative party candidate Conrad Weidenhammer in 1913, who chose to retire after a single term.

He ran again in the 1921 election, but was defeated by United Farmers candidate Willard Washburn in a landslide.

Macleod was defeated in 1935, finishing a very distant third place to Social Credit candidate William Hayes.

Cornelia Wood was nominated to be the Social Credit candidate, she won the district for her party in a tight race that went to ballot transfers.

Wood lost her nomination race to run as the Social Credit candidate again in the 1967 general election to Ralph Jespersen.

Jespersen would only last a single term in office before being defeated by William Purdy in the 1971 general election.

Fred Lindsay replaced Woloshyn in 2004 as the Progressive Conservative MLA for the riding and was re-elected in 2008.

The last person to represent Stony Plain was Erin Babcock, who won the riding for the Alberta New Democratic Party in the 2015 election.

The plebiscite was intended to deal with the growing demand for reforming antiquated liquor control laws.

The vote was designed to educate students and simulate the electoral process for persons who have not yet reached the legal majority.
