Chauny is a commune in the Aisne department in Picardy in northern France.


Built on the banks of the Oise and the Saint-Quentin canal, the town still retains its port to this day. Chauny is equal distances from Soissons (34 km), Laon (36 km) and Saint-Quentin, Aisne (30 km) and is right at the heart of Picardy.

Chauny is well linked to the rest of the region by road : close to the A26 and A29 motorways which head towards Saint Quentin. The national airports in Paris are an hour by car.

The town is served by an important railway network and the railway line has passed through the town since 1849. The railway station in Chauny is part of the Paris - St Quentin - Maubeuge line, and is well serviced by Corail and TER trains towards Paris, Compiègne and Saint Quentin. The station was re built after the war to plans by Urbain Cassan.

The Saint-Quentin canal was built as a junction between the Somme and the Oise in 1738, is popular with barges.

A very modern theatre often shows cultural exhibitions and performances. Close by are the forests of Saint-Gobain and Coucy Basse.


The town today has three collèges and four lycées : there is a scientific, technical and professional lycée, Jean Macé, a general and technical lycée, Gay-Lussac, a private lycée, Saint-Charles, and a private agricultural lycée, Robert Schuman.
