Lakeside is a provincial electoral division in Manitoba, Canada. It is located to the immediate northwest of the city of Winnipeg.
Traditionally a rural riding, Lakeside has become more urban in recent years (as a result of both electoral redistribution and changes in demography). All the same, agriculture accounted for 17% of the riding's industry in 1999. The riding is bordered to the north by Interlake, to the west by Portage la Prairie, to the south by Morris and to the east by Gimli. It also borders the city of Winnipeg to the southeast.
Lakeside's population in 1996 was 19473. The average family income in 1999 was C$49,774, with an unemployment rate of 6.10%. Eight per cent of the population is of a German background, and 8% are aboriginal.
Lakeside was created by provincial redistribution in 1886. It has traditionally elected representatives of agrarian interests, both of the Liberal and Progressive Conservative parties. Since 1922 to the present, the riding has had only three representatives.
