Yellowknife Post Office, Modern post office in Yellowknife, Canada

The Yellowknife Post Office is a two-storey concrete building at the southwest corner of 49th Street and Franklin Avenue, completed in 1956 in a late modernist style. Its timber frame is faced in concrete with a flat roof, and a three-bay pavilion rises an extra storey at the rear. The building housed the territorial courts until 1978.

The post office opened in 1956 as Yellowknife expanded beyond its Old Town district and needed centralized postal infrastructure. This timing marked an important phase when the city required better communication links with distant regions.

A city councillor recalled that in the 1960s "this is where you went to find everybody", and the building kept that role as a downtown social centrepiece, recognised when its heritage plaque was unveiled in 2010. In 2014, after the city removed the benches outside in response to complaints about the behaviour of local homeless people, residents held a sit-in protest there.

The post office stands at the southwest corner of 49th Street and Franklin (50th) Avenue, on level ground at the top of the rise from Great Slave Lake. The main entrance is recessed into the corner under a low porch with metal railings; a secondary entrance with metal and glass doors faces the east side. A parking lot of roughly the building's own area lies to its west, and broad stone-tiled sidewalks run along the north and east sides.

The building housed the territorial courts until 1978, so mail and justice shared one address for over two decades. In 2014 the city removed the benches outside, prompting a sit-in protest by local residents. Look for the heritage plaque added in 2010, when a councillor recalled that in the 1960s "this is where you went to find everybody."
