Lindenlea is possibly one of the smallest neighborhoods in Ottawa, Canada. It is bounded by Mariposa Ave. to the north, Acacia Ave. to the east, Beechwood Ave. to the south and Springfield Rd. to the west. Its neighbouring communities are Rockcliffe Park (north and east), Vanier (south) and New Edinburgh (west).

Lindenlea has a children's park, tennis courts and a community centre. It is the earliest planned community in Ottawa, dating back to the end of the First World War. The community was planned by urban planning pioneer Thomas Adams and is an example of Adams' garden suburb style.

Most of the homes have large back yards, a feature of this planning style. The community is divided into upper Lindenlea, north of Rideau Terrace, and lower Lindenlea. Only upper Lindenlea was planned by Adams. Lower Lindenlea was developed later but followed many of the garden suburb principles, including the large back yards.

Lindenlea is notable for its picturesque architecture, mature trees, and plentiful green space. The community association produces a periodic newsletter called The Lindenleader and residents of Lindenlea also receive The New Edinburgh News produced by the community association of neighbouring New Edinburgh.
