NK Lokomotiva Zagreb is a professional Croatian football club based in Zagreb. It competes in the Prva HNL, the country's top division. Founded in 1914, the club's only period of success came in the late 1940s and early 1950s before spending most of the following five decades as lower-level minnows.
In the mid-2000s Lokomotiva was turned into Dinamo Zagreb's farm team. Between 2007 and 2009 they won three consecutive promotions to rise from fourth level to first level in the Croatian football league system. They hosted their home matches at Dinamo's Stadion Maksimir for a couple of years before moving to NK Zagreb Stadion Kranjčevićeva, as their own ground in the Novi Zagreb's Kajzerica neighbourhood is unsuitable for top level football. They remain Dinamo's unofficial feeder club even when playing against them in 1. HNL, thus sparking numerous controversies.
