Tarn-et-Garonne is a department in the Occitania region in Southern France. It is traversed by the rivers Tarn and Garonne, from which it takes its name. The area was originally part of the former provinces of Quercy and Languedoc. The department was created in 1808 under Napoleon, with territory taken from the neighbouring Lot, Haute-Garonne, Lot-et-Garonne, Gers and Aveyron departments.
