Quimper (US: /kæ̃ˈpɛər/,[3] French: [kɛ̃pɛʁ] ⓘ; Breton: Kemper [ˈkẽmpəʁ]; Latin: Civitas Aquilonia or Corisopitum) is a commune and prefecture of the Finistère department of Brittany in northwestern France.

Quimper is the ancient capital of Cornouaille, Brittany's most "traditional" region, and has a distinctive Breton-Celtic character, from music and dance traditions to linguistics and genetics; indeed, the historical name is also somewhat similar to "Cornwall", a region in southern England with distant cultural similarities.

The Cathedral of Saint-Corentin, with its Gothic-style façade, was constructed between the thirteenth and sixteenth centuries, and is the oldest Gothic structure in lower Brittany.

Near the Episcopal palace (which now holds the Musée départemental Breton, devoted to regional history, archaeology, ethnology and economics) are the ruins of the town's fifteenth-century walls.

It houses a collection of 14th to 21st-century paintings, including works by François Boucher, Jean-Baptiste-Camille Corot, Jean-Baptiste Oudry and Peter Paul Rubens, along with canvases by such Pont-Aven School painters as Émile Bernard, Maurice Denis, Georges Lacombe, Maxime Maufra and Paul Sérusier.

Quimper has also been known for copper and bronze work, galvanised ironware, hosiery, leather, paper and woollen goods, as well as being a gastronomic destination for its varied regional dishes.

Harré’s body washed ashore in Scotland and was buried in Doune Cemetery in Girvan, South Ayrshire.

A wreath was laid on behalf of the mayoress of Quimper and the city, symbolizing the historic ties between the French and Scottish communities, and commemorating the sacrifice of the sailors.

The municipality launched a linguistic plan through Ya d'ar brezhoneg on 6 February 2008, to revive the teaching and use of Breton, the historic Celtic language of the region.

The Gare de Quimper is the terminus of a TGV high-speed train line from Paris, which passes through Le Mans, Rennes and Vannes.
