Musée naval de Québec, Maritime museum in Old Port, Quebec City, Canada.

The Naval Museum of Quebec, also called the Stanislas-Déry Naval Museum, occupies a building at 170 Dalhousie Street in the Old Port. Since 15 June 2023 its facade carries a 200-metre fresco by Quebec artist Paul Abraham, made of 28 printed canvas panels fixed over the walls and windows like ships' sails. Inside, the permanent exhibition Héritiers des Guerres gives voice to descendants and relatives of sailors who lived through the Second World War.

The museum opened on 20 May 1995, following the installation of the Pointe-à-Carcy naval complex in the Old Port. It is one of the 73 official museums of the Canadian Armed Forces and grew from a handful of artefacts to several thousand pieces in Quebec, plus tens of thousands more held in the 24 Naval Reserve units between Newfoundland and British Columbia. In 2010, for the centenary of the Canadian Navy, it presented its first full retrospective of naval history on the St. Lawrence and was official presenter of the second Quebec naval rendezvous, held 3–6 June 2010.

The museum bears the name of Stanislas Déry, and its approach, called the theory of impacts, holds that military museums should raise public awareness of the effects of war and the value of peace. Temporary shows have paired contemporary art with naval history, as in Le Réfectoire in 2008.

The museum is at 170 rue Dalhousie, in the Old Port of the lower town, a short walk from Place Royale and the Pointe-à-Carcy naval complex. It is one of the 73 official museums of the Canadian Armed Forces. Check opening days before going, since the museum has long combined its own displays with travelling exhibitions made with partner institutions.

The collection includes detailed records of ship movements and activities on the St. Lawrence River that document both military operations and commercial traffic over time. These archives allow visitors to see how the waterway shaped economic and social life in the region.
