Lake Bonavista is a neighbourhood in Southeast Calgary, Alberta, Canada. It is bounded by Anderson Road to the north, Macleod Trail to the west, Canyon Meadows Drive to the south, and Bow Bottom Trail to the east. The small community of Bonavista Downs resides in the northeast corner of the neighbourhood.

Lake Bonavista was developed by the Keith Construction company starting in 1967. It was the first community in Canada to be built around a man-made lake, and served as a prototype for other lake communities in Calgary.

Two trailer courts were on the west side of Bonavista, north of the Avenida Shopping Centre, alongside Macleod Trail. The Avenida shopping centre, opened in 1988, was built to cater to the increasing size of the neighbourhood. It includes an art gallery and assorted upmarket restaurants.

Lake Bonavista Promenade is a small commercial development within Lake Bonavista that includes both retail space and professional offices. There is convenient access to shopping areas along Macleod Trail and in Southcentre Mall.

Fish Creek Park borders the community to the south, and provides a variety of outdoor recreation opportunities.

The Lake Bonavista Community Association (not to be confused with the homeowners association which maintains the lake) owns a community centre within the district. The centre includes two ice rinks, a gym, and a variety of multipurpose rooms.

There is also a City of Calgary ice rink, Frank McCool Arena, within the community.

The area was originally flat treeless prairie with no distinctive natural features. In order to make the area more attractive, Lake Bonavista, a 52-acre (210,000 m) manmade lake, was constructed in 1968, with a portion of the earth excavated from the lake used to construct a 65-foot (20 m) hill with a waterfall adjacent to the lake. The lake and park provide a variety of year-round recreational opportunities for residents, including fishing, swimming, boating, tennis, skating, and tobogganing. The Lake Bonavista Homeowners Association, membership of which is mandatory for homeowners in the area, provides for the upkeep of the lake and park.

The neighbourhood also contains a second manmade lake, Lake Bonaventure. This 35-acre (140,000 m) lake is only accessible from houses built directly around the lake itself. Homeowners with access to Lake Bonaventure must pay their share of the upkeep on both Lake Bonavista and Lake Bonaventure.

Bonavista Downs residents share many of the amenities with Lake Bonavista, but they do not have access to the lakes and do not pay for their upkeep.
