The TMK 2200 (also known as NT 2200) is a low-floor tram that operates in Zagreb, the capital of Croatia.

Zagreb Electric Tramways, the city public transportation company), ordered 70 vehicles in 2003 after Crotram consortium won the tender on the ground of lower price, competing with offers by Siemens (Combino) and AnsaldoBreda (Sirio).

Satisfied with the quality of the trams, ZET ordered another 70 vehicles in mid-2007, which are due to be delivered by May 2009.

Although Croatian press articles have suggested many operators being seriously interested in the TMK 2200, the more concrete arrangements so far have been: The tram is 32 meters long, with three bogeyed and two fully suspended articulated sections, but the modular construction allows longer and shorter versions using the same design of the sections.

Maximum speed is electronically limited to 50 km/h (31 mph), and the trams are equipped with air-conditioning and CCTV cameras.
