The Wielkopolski is a breed of horse that was originated in Central and Western Poland in 1964, and is occasionally known as Mazursko-Poznanski.

The Wielkopolski was developed by crossing two now extinct Polish breeds, the Pozan and the Mazury, so it is also referred to as the Mazursko-Poznanski.

Although not a well-known breed worldwide, it is used as a sport horse because of its temperament, comfortable gaits, and hardiness.

The Wielkopolski has a fine, small head with a straight profile and lively eyes.

They can be any solid color, and usually stand between 15.2 and 16.2 hands (62 and 66 inches, 157 and 168 cm) There is also another Polish warmblood breed, the Małopolski, bred in the region of Małopolska ("Little Poland") in the south of the country (around Kraków).
