The Buick V6 is an OHV V6 engine developed by the Buick division of General Motors and first introduced in 1962. The engine was originally 198 cu in (3.2 L) and was marketed as the Fireball engine. GM continued to develop and refine the 3.8 L (230 cu in) V6, eventually and commonly referred to simply as the 3800, through numerous iterations.

The 3800 made the Ward's 10 Best Engines of the 20th Century list and made Ward's yearly 10 Best list numerous times. It is one of the most-manufactured engines in automotive history, with over 25 million produced.^{[citation needed]}

The engine originally derived from Buick's 215 cu in (3.5 L) aluminium V8 family,^{[citation needed]} which also went on to become the Rover V8, manufactured from 1960–2006.
