Osgoode Ward (Ward 20) is a municipal ward located in the rural southeast corner of the City of Ottawa. It mostly consists of the former Osgoode Township and parts of the former city of Gloucester and Cumberland. It has been represented on Ottawa City Council by Isabelle Skalski since her election in a by-election in June 2025.

The ward contains the communities of Greely, Osgoode, Metcalfe, Vars, Edwards, Carlsbad Springs, Kenmore, Vernon, South Gloucester, Ficko, Limebank, Johnston Corners and Piperville.

The ward was created for the 2000 municipal elections in preparation for Osgoode Township's amalgamation into the city of Ottawa. From 1994 to 2000, Osgoode Township was located in Cumberland-Osgoode Ward on the Regional Municipality of Ottawa-Carleton regional council. From 1969 to 1994 the mayor/reeve of the Township was the area's representative on regional council.

From 2000 to 2006, the ward consisted solely of the former Township of Osgoode. Beginning with the 2006 election, the boundaries changed to add much of rural southern Gloucester to the ward. And, beginning with the 2022 election, the ward expanded further to include more of rural Gloucester, plus southern and southwestern portions of the former Cumberland Township.

There will be a by-election on June 16, 2025 to replace Darouze who had been elected to the Legislative Assembly of Ontario earlier in the year.
