Tonnay-Charente (in French pronounced as /tɔnɛ ʃaʁɑ̃t/) is a commune in the Charente-Maritime department, administrative region of Nouvelle-Aquitaine, France.
In the 18th century, it was the home town of prominent Irish physician Dr. Theobald Jennings and his son, Irish-born French General Charles Edward Jennings de Kilmaine who fought in the American War of Independence and, more significantly, in the French revolutionary wars with Napoleon I of France. There is a personal portrait of General Kilmaine in the Hôtel de Ville (City Hall) of Tonnay-Charente. Rue Kilmaine, a street in Tonnay-Charente was named in his honour.
