Jaktorów is a village in Grodzisk Mazowiecki County, Masovian Voivodeship, in east-central Poland. It is the seat of the gmina (administrative district) called Gmina Jaktorów. It lies approximately 8 km west of Grodzisk Mazowiecki and 37 km southwest of Warsaw. The last recorded aurochs (Bos taurus primigenius), a female, died in 1627 in the Jaktorów Forest, Poland. Also called the urus (in Polish tur), aurochs were the ancestors of domestic cattle, inhabiting Europe, Asia, and North Africa. The skull of the last recorded specimen was later looted by the Swedish Army during the Swedish invasion of Poland (1655–1660) and is now in Livrustkammaren in Stockholm.
