The InterRegio in Switzerland was first introduced in {{start date and age|1997|p=y}}. They replaced some of the former fast trains with their own identity. InterRegio trains run from region to region within Switzerland. One service extends to the German city of [[Konstanz]], just across the [[Germany–Switzerland border|border]].

InterRegio trains are now very commonplace in Switzerland. The abbreviation is '''IR''' in a 45°-edgy font, white letters on red ([[File:InterRegio logo SBB CFF FFS.jpg|60px]]). Since the early 2020s, most IR services are numbered and each has a distinct colour.

The [[ICN (SBB-CFF-FFS)|ICN]] runs as an [[InterCity (Switzerland)|InterCity]] (IC) train but sometimes with halt frequencies in the same manner as an IR ([[Geneva]]/[[Lausanne]]-[[St. Gallen]]/[[Basel]] route). When ICN services first began on 28 May 2000, the ICN was placed as an InterRegio train. {{As of|2025}}, SBB [[SBB Re 460|Re 460]]-[[push-pull train|hauled]] [[IC 2000]] cars and [[RABe 511]] or [[SBB RABe 502|RABe 502]] [[electric multiple unit|EMUs]] operate as IR services on several routes, while some routes are operated by SOB [[SOB Traverso|RABe 526]], BLS [[BLS RABe 528|RABe 528]] or other.

{{As of|alt=As of the December 2024 timetable change|2023|12|post=,}} the following InterRegio services exist, operated by [[Swiss Federal Railways|SBB CFF FFS]], [[BLS AG|BLS]], [[Rhaetian Railway|RhB]] and [[Südostbahn|SOB]]:
