17 Avenue SE is a major arterial road in east Calgary, Alberta.

It passes through the communities of Albert Park/Radisson Heights, Southview, and Forest Lawn, and continues east past Elliston Park before intersecting Stoney Trail.

17 Avenue SE is the original alignment of Highway 1 through eastern Calgary.

[3] In 2007, the City of Calgary annexed land from Rocky View County up to Range Road 284 (now 116 Street SE);[4] while in 2009, Chestermere annexed land up to the Calgary city limit,[5] resulting in Highway 1A no longer travelling through a rural municipality and signaling a possible end to the Highway 1A designation.

Long-term plans call for the mixed-use corridor and transitway to extend east into Chestermere.
