The BMW M3 is a high-performance version of the BMW 3 Series, developed by BMW’s in-house motorsport division, BMW M GmbH. M3 models have been produced for every generation of 3 Series since the E30 M3 was introduced in 1986.

The initial model was available in a coupé body style, with a convertible body style added soon after. M3 saloons were available during the E36 (1994–1999) and E90 (2008–2012) generations. Since 2014, the coupé and convertible models have been rebranded as the 4 Series range, making the high-performance variant the M4, so that generation of 3 Series saw the M3 produced only as a saloon. In 2020, the M3 was produced as an estate (Touring) for the first time, alongside the saloon.
