Wooler was a British manufacturer of motorcycles and automobiles, founded by engineer John Wooler in 1911 based in Alperton, Middlesex. The company became known for its unconventional designs which included several fore-and-aft twins, a vertical camshaft single cylinder machine, a transverse-four beam engine, and a transverse flat four. Most machines possessed Wooler’s enduring design features of a petrol tank which extended past the steering head.

In 1919-1920 the Wooler Mule cyclecar was manufactured until the company was reformed.
