Marda Loop is a shopping and dining district (i.e., a Business Improvement Area, or BIA) in southwest Calgary, Alberta, Canada.

It intersects the neighbourhoods of South Calgary, Altadore, Garrison Woods, and the southeastern part of the community of Richmond-Knob Hill.

[5][6][7][8] What is now the Marda Loop Communities Association was established on 6 September 1957 to support the residents of this area and the broader South Calgary during the huge postwar growth period of the 1950s.

In the late 1990s, however, the community saw a major change due to the departure of nearby Canadian Forces Base Calgary and the closure of the PMQ (Permanent Married Quarters) area.

In 2004, the PMQs were redeveloped as the 161-acre Garrison Woods by Canada Lands, including a residential area with 1,600 homes and many new shops grew the Marda Loop business district.
