Proszowice County (Polish: powiat proszowicki) is a unit of territorial administration and local government (powiat) in Lesser Poland Voivodeship, southern Poland. It came into being on January 1, 1999, as a result of the Polish local government reforms passed in 1998. Its administrative seat is Proszowice, which lies 31 kilometres (19 mi) north-east of the regional capital Kraków. Its only other town is Nowe Brzesko (since 2011).
The county covers an area of 414.57 square kilometres (160.1 sq mi). As of 2006 its total population is 43,441, out of which the population of Proszowice was 6,205 and the rural population was 37,236.
Proszowice County was disbanded by Austrian authorities in 1794, and most of its territory was merged into District of Miechów. From 1815 until 1916, most of former county belonged to Russian-controlled Congress Poland. Separated by Austro-Russian border from the city of Kraków, the region stagnated, with Proszowice losing its town charter in 1864.
In the Second Polish Republic, Proszowice regained town rights in 1923, but was not named seat of a county. After World War II, Proszowice belonged to Miechów County until 1954, when Proszowice County was recreated. It existed until 1975 when all counties were disbanded (see Administrative division of the Polish People's Republic).
