Calgary-South East provincial electoral district also known in its former incarnation as the Calgary South East electoral district from 1959 to 1963 is a proposed electoral district under the 2010 boundary redistribution and a historical electoral district.
The first district was very short lived. It was created from the Calgary electoral district in the 1959 boundary redistribution and redistributed in the 1963 boundary redistribution when it became part of the Calgary South electoral district.
The historic 1959 redistribution of the provincial ridings of Calgary and Edmonton marked the transition to standardize First Past the Post across the province. From 1926 to 1959 Calgary and Edmonton, elected members with Single Transferable Vote. The rest of the ridings in the province had the option of how to count votes during that period. The redistribution created seven ridings in Calgary of which two currently exist.
This transition was done in part to standardize the electoral system across the province and because Calgary and Edmonton were becoming two large to be a single riding.
