The Consorcio Regional de Transportes de Madrid (CRTM; literally: Regional Consortium of Transportation for Madrid) is an autonomous body created by Spanish law 5/1985 which is tasked with coordinating the public transport operations across multiple providers in the Community of Madrid.

[3][4] It harmonizes fares for commuter rail, rapid transit, light rail and bus transport services provided by entities such as Renfe Cercanías, Metro de Madrid S.A. or the Empresa Municipal de Transportes de Madrid (EMT).

[5][6] Its executive board is presided by the regional minister for Transportation.

[7] Intercity transport, i.e. journeys that go between different municipalities in the Madrid region, are operated by the CRTM.

[8] The inter-urban night buses (autobuses interurbanos), commonly known as Green Owls (Búhos verdes), travel further afield than the regular N1 to N28 and NC1-NC2 owl buses within Madrid urban core (which are operated by EMT), and connect Madrid with the smaller cities of the periphery.
