Park Kultury i Wypoczynku Mazowsze w Pruszkowie, Urban park in Pruszków, Poland.

Park Mazowsze is an urban park in the Żbików district of Pruszków, covering 9.8 hectares, of which 5 hectares are water. Its two reservoirs are linked by a dug channel, and a wooden pier and new footpaths run along them. The grounds also hold an outdoor gym, a small rope park, a playground, a campsite field and a car park.

The land was a clay pit for brick production in the 19th century before the Hoser family established a plant nursery and garden complex on the site. This transformation from industrial extraction to green space shaped what the place became.

Locals call the park Glinki Hosera, after the Hoser family's clay pits. The ponds are a fishing ground leased by the Polish Angling Association, which stocks carp, tench and crucian carp each autumn and pike in spring. In 2009 the park received a distinction from the Marshal of the Mazowieckie Voivodeship in the "Most Beautiful Park of Mazovia" competition.

The park is easy to reach on foot and has flat paths suitable for visitors of all ages and abilities. The swimming area operates only during warmer months, so plan your visit accordingly if water activities are your goal.

The water reservoirs formed from iron-rich clay extraction and now support fishing, with regular stocking of carp, tench, and pike for anglers. This repurposing demonstrates how nature was restored on former mining grounds.
