Milicz County (Polish: powiat milicki) is a unit of territorial administration and local government (powiat) in Lower Silesian Voivodeship, south-western Poland.

The Milicz County is made up of three boroughs: Milicz, Krośnice, and Cieszków. The county is famous for its forests and ponds. The Milicz Ponds built in the 13th century by the Cistercian monks are nowadays the biggest centre of carp-culture in Poland. The unique flora and fauna of this region were the main reason for which the Nature Centre "the Barycz Valley" was set up here. The Milicz County provides suitable conditions for development of small and average businesses. The county possesses also many grounds prepared for investments - in order to encourage new investors, the local authorities offer them tax privileges. The most important investment carried out over the last few years is the enlargement of the local hospital. The institution opened in 1999 is now a modern establishment providing patients with medical services. The hospital, which has 240 beds at its disposal, possesses 9 common and specialistic departments. The institution has also specialistic dispensaries offering services in the fields of common surgery, traumatology, orthopaedic surgery, gynaecology, allergology, ophthalmology and treatment of glaucoma, otolaryngology, treatment of tuberculosis, and illnesses of lungs.
