Alexander Ross (15 January 1880 – 17 July 1953) was a stonemason, trade unionist and politician in Alberta, Canada.

He was elected as the first and only member of the Labor Representation League to sit in the assembly.

In that election the United Farmers of Alberta defeated the Liberals in the rural part of the province, and formed the government.

The United Farmers did not run any candidates in Calgary and Ross was asked to serve as Minister of Public Works despite being a member of the opposition.

Ross placed sixth in the First Count ahead of five others including fellow Labour candidate Fred White.
