Ellen Fairclough Building, Provincial government building in Hamilton, Canada.

Ellen Fairclough Building is an 18-storey, 94-metre office tower at King Street West and MacNab Street South in Hamilton. Completed in 1981, it houses provincial government offices, a courthouse, and a citizenship and immigration office. The Hamilton Convention Centre occupies the first three floors, and an enclosed pedestrian bridge over King Street links the tower to Lloyd D. Jackson Square and the Sheraton Hamilton.

Opened in 1981 as the Convention Centre, the tower was renamed the Ellen Fairclough Building in 1982 after the Hamilton-born politician who served 13 years in Parliament under John Diefenbaker and became Canada's first female Cabinet member. She pressed for gender equality and fairer immigration policy, and died in 2004 at 99.

The Hamilton Convention Centre occupies the tower's first three floors, except the ground-floor lobby and shared loading dock. The building is attached to the Art Gallery of Hamilton and FirstOntario Concert Hall, and an enclosed pedestrian bridge over King Street links it to Lloyd D. Jackson Square mall and the Sheraton Hamilton hotel.

A covered bridge connects the building directly to Jackson Square, where you will find shops and additional facilities within walking distance. The central location makes it easy to explore the surrounding downtown area on foot.

The building's name honours Ellen Fairclough, a Hamiltonian who served 13 years in Parliament under John Diefenbaker and died in 2004 at 99. She was the first woman in the Canadian Cabinet. The tower opened in 1981 as the Convention Centre and was renamed for her a year later.
