The term '''Cadillac V8''' may refer to any of a number of [[V8]] engines produced by the [[Cadillac|Cadillac division]] of [[General Motors]] since it pioneered the first such mass-produced engine in 1914.<ref>{{cite press release|url=https://media.gm.com/media/me/en/cadillac/news.detail.html/content/Pages/news/me/en/0000/Cadillac/00_00_history_100years_Technology.html#:~:text=A%20born%20winner%3A%20Cadillac%20inspired,eight%2Dcylinder%20in%20V%2Dform&text=This%2C%20the%20first%20mass%2Dproduced,year%20between%201927%20and%201929|title=Cadillac - 100 Years of Innovation and Progress - Pioneering technical achievements|date=January 1, 2009|website=Cadillac Pressroom}}</ref>

Most commonly, such a reference is to one of the manufacturer's most successful, best known, or longest-lived 90° V8 engine series. These include the pioneering [[overhead valve]] [[#331 series|{{cvt|331|cuin|L|1}}]] cu in introduced in 1949, made in three displacements up to {{cvt|390|cuin|L|1}}; a [[#390 series|{{cvt|390|cuin|L|1}}]] introduced in 1963 that grew to [[#429 series|{{cvt|429|cuin|L|1}}]]; and a [[#472 series|{{cvt|472|cuin|L|1}}]] introduced in 1968 and enlarged to {{cvt|500|cuin|L|1}}. Also notable was the [[#Northstar|Northstar]], which debuted in 1992 as a 4.6 litre, and was also produced in 4.4 L and 4.2 L versions.

When the [[Northstar engine series]] ended production in 2010, it became the last [[General Motors Corporation|General Motors]] division to retain its own proprietary V8 design. This changed when Cadillac created the twin-turbo "[[Cadillac twin-turbo V8|Blackwing]]" engine in 2019.
