Dow's Lake (French: Lac Dow, formerly known as Carling) is an O-Train station on the Trillium Line, one block west of the intersection of Carling Avenue and Preston Street in Ottawa, Ontario.

It is named after the nearby Dow's Lake, itself also the western terminus of the Rideau Canal skating rink during winters, as well as a key site during the Canadian Tulip Festival in May.

The station is also near government offices at the area of Carling Avenue and Booth Street.

South of Carling, the train enters a tunnel to pass under the Rideau Canal.
