Olszynka Grochowska is a subdistrict located in the northern part of Praga-Południe, in southeastern Warsaw.[1] The subdistrict is primarily forested, but it also features a nature reserve and the railway station.
The area is historically significant as the site of the Battle of Olszynka Grochowska, which occurred on 25 February 1831 during the November Uprising.
