The TeST TST-3 Alpin T (Alpine) is a Czech shoulder-wing, T-tailed, single-seat glider and motor glider that was designed and produced by TeST of Brno.

Design and development
The TST-3 was produced in many forms, including as plans and kits or various levels of completion for amateur construction and also as a factory completed aircraft. It was produced as a motor glider with a retractable engine and also as a pure glider. Production is complete and the type is no longer available.

The TST-3 is of mixed construction, using fibreglass, wood and aircraft fabric covering. The 13.4 m span wing is equipped with winglets and a Wortmann FX 61-184 airfoil. The tractor configuration Hirth F-33 16 kW motor is mounted on a strut that retracts aft into a bay behind the cockpit and is enclosed by two doors. A Rotax 503 of 37 kW was optional. The landing gear is retractable monowheel gear.
