Knox Presbyterian Church, Ottawa

Knox Presbyterian Church, situated in Ottawa, is a Presbyterian Church that bears the name of John Knox, a prominent figure in the establishment of Presbyterianism in Scotland.

The original Knox Church, designed by Donald Kennedy in 1845, was situated in Sandy Hill at the intersection of Daly Avenue and Cumberland. In 1874, the Knox congregation relocated downtown, leaving their building to Saint Paul's Presbyterian, which later became Saint Paul's-Eastern United Church (Eastern Methodist) following the church union in 1925.

The second Knox Church, located near the Second City Hall (Ottawa) on Elgin Street, now occupied by the National Arts Centre, housed the Regimental and King's Colours of the 207th Battalion in 1919. These artifacts are now displayed in the current church, along with a plaque honoring the memory of the 207th Battalion, CEF veterans.

In 1930, the City of Ottawa expropriated the area to widen Elgin Street, compelling Knox Church, which had remained part of the Presbyterian Church in Canada since 1925, to move a few blocks away to its current location at the corner of Lisgar and Elgin. The second church was subsequently demolished in 1932.

The present-day Knox Church building, designed by John Albert Ewart and Henry Sproatt in 1931, was opened in 1932. The church has had the honor of hosting the General Assembly of the Presbyterian Church in Canada on three occasions.
