Bösel is a municipality in the district of Cloppenburg, in Lower Saxony, Germany.

Bösel was first mentioned in 1080 under the name Borsla (= "Forest at a wavy bank") in a testimonial of the bishop of Osnabrück.

The first written document of a chapel in Bösel is dated with the year 1574, but Bösel was not separated from its mother church in Altenoythe and made an independent commune until 1876. Today Bösel consists of nine areas (Bösel-Ort, Edewechterdamm, Glaßdorf, Hülsberg, Osterloh, Ostland, Overlahe, Petersdorf und Westerloh).
