Alan was a German automobile manufacturer active from 1923 to 1925, founded by J. Mayer in Bamberg, Germany. The company emerged during a period when numerous automotive brands were attempting to establish themselves in the competitive market of the 1920s. However, like many of its contemporaries, Alan struggled to maintain a foothold and ceased operations shortly after its inception.

The sole model produced by Alan was the 6/30PS, which was equipped with a 4-cylinder engine sourced from Siemens & Halske. Despite its brief existence, Alan represents a chapter in the history of early 20th-century German automotive endeavors, reflecting the challenges faced by many manufacturers during that era.
