Edmonton-Decore is a provincial electoral district in Alberta, Canada. It is one of 87 districts mandated to return a single member to the Legislative Assembly of Alberta using the first past the post method of voting. It was most recently contested in the general election of 2019.

The riding is located in north central Edmonton. It was created in the 2004 boundary redistribution out of a small part of Edmonton-Manning and most of Edmonton-Glengarry. The riding is named after Laurence Decore, former Leader of the Opposition and Mayor of Edmonton.

Neighborhoods in this riding include: Kildare, Killarney, Northmount, Evansdale, Belle Rive, Mayliewan, Delwood, Glengarry & Balwin.

The riding has been held by representatives of the Progressive Conservative, Liberal, and New Democratic parties since it was created. The current representative is New Democratic Party MLA Sharif Haji, who was first elected in the 2023 general election.

The electoral district was created in the 2004 boundary redistribution from Edmonton-Glengary and Edmonton-Manning, and was first contested in the general election of 2004. The 2010 boundary redistribution saw the major changes made to the riding.

The western boundary with on 97 Street between the Edmonton city limits and 167 Avenue Edmonton-Castle Downs was moved east to cede land to that constituency. The south boundary with Edmonton-Highlands-Norwood was changed to move along 127 Street instead of the Canadian National Railway tracks. The east boundary saw significant changes as it was pushed eastward to 66 Street into Edmonton-Beverly-Clareview and Edmonton-Manning as far north as 144 Avenue from the railway tracks at 127 Street. The east boundary with Edmonton-Manning was also realigned to run on 66 Street north of 153 Avenue to give some land to Manning.

On November 19, 2004, a student vote was conducted at participating Alberta schools to parallel the 2004 Alberta general election results. The vote was designed to educate students and simulate the electoral process for persons who have not yet reached the legal majority. The vote was conducted in 80 of the 83 provincial electoral districts with students voting for actual election candidates. Schools with a large student body that reside in another electoral district had the option to vote for candidates outside of the electoral district then where they were physically located.
