The TRML (German: Telefunken Radar Mobil Luftraumüberwachung, or "Telefunken mobile airspace surveilance radar") is a family of air defense radars first developed by Telefunken and currently produced by Hensoldt. It is a development of the earlier TRMS (German: Telefunken Radar Mobil Such or "Telefunken mobile search radar").

Retractable mast versions are TRML-2D with a rotating parabolic antenna and TRML-3D with a rotating phased array antenna, designated as Nahbereichsradar (NBR) or "short range radar" by the Bundeswehr. The latest TRML-4D comes with non-retractable, rotating base active electronically scanned array (AESA) solid-state antenna.
