In Poland, interREGIO trains were introduced by [[Przewozy Regionalne]] (PR) in spring of {{start date and age|2009|p=y}}, the first IR train connecting [[Białystok]] with [[Warsaw]]. The fare is similar as ''TLK''-branded fast trains of [[PKP Intercity]].

In the beginning these trains operated mostly on Fridays and Sundays along the routes: [[Wrocław]]-[[Kraków]], Kraków-[[Przemyśl]], [[Poznań]]-[[Olsztyn]], Poznań-Warsaw and [[Bydgoszcz]]-Warsaw. Since June 2009 there are more interREGIO trains on routes; most of them are available through the whole week, some of them only on weekends. More routes were introduced, some of which are especially made for students, like [[Kielce]]-[[Częstochowa]]-Wrocław.

InterREGIO in Poland mostly uses older [[electric multiple unit]]s (usually [[PKP class ED72|ED72]], [[PKP class EN71|EN71]] and [[PKP class EN57|EN57]]), with newer units on some routes ([[PKP class ED73|ED73]] and [[PKP class ED59|ED59]] between Warsaw and [[Łódź]], [[14WE]] between Kraków and Warsaw). Some IR trains are serviced with single- and/or [[Bilevel rail car|double-decker cars]] and locomotives.

{{As of|2009|1|1}}, all IR trains in Poland are second class-only, even though PR's regulations include a first-class fare for interREGIO trains and in service are first-class coaches, yet declassified.

On 3 March 2012, the [[Szczekociny train collision]] occurred, with 15 deaths and 50 injured.

Since 1 September 2015 IR trains are only on routes [[Łódź]] – [[Warsaw|Warszawa]] and [[Ełk]] – [[Grodno]] (Belarus), due to company's economics and restructuring.<ref>{{cite web|title=Zmiany w ofercie Przewozów Regionalnych|url=http://www.przewozyregionalne.pl/node/18425|publisher=Przewozy Regionalne|access-date=18 September 2015|language=pl}}</ref> The rest were withdrawn or replaced by [[PKP Intercity|''Twoje Linie Kolejowe'']] express trains.
