Public transport in Debrecen, Hungary, is provided by DKV (short for Debreceni Közlekedési Vállalat – Public Transport Company of Debrecen; complete name is DKV Zrt.)
Before mid-2009 two companies provided public transport in the city: trams and trolleybuses were operated by DKV while buses were operated by Hajdú Volán, which provides transport in the rest of Hajdú-Bihar county. DKV took over bus transport on 1 July after winning a tender. DKV has 140 buses (40 of which are articulated buses). All buses are Low-floor and airconditioned.
