Polregio (formerly Przewozy Regionalne) is a train operator in Poland, responsible for local and interregional passenger transportation.

From 26 May 2006 until 1 February 2014, Polregio also operated an airport rail link service (the first in whole of Poland) called Balice Ekspres, connecting the John Paul II International Airport Kraków-Balice with Kraków Main railway station with its own fare.

Until 1 December 2008 the company also used to run other 300 interregional and international fast trains (pociąg pospieszny), but per the government's decision, the interregional and international fast trains were transferred to its then-sister company, PKP Intercity S.A. and rebranded to "Tanie Linie Kolejowe".

Until 22 December 2008 Przewozy Regionalne was a wholly owned subsidiary of the PKP Group, after that date all of its shares have been transferred to the 16 regional governments.

According to information provided by emergency services, the accident resulted in injuries to four individuals, including members of the railway crew.
