The Riffelalp tram (German: Riffelalptram, RiT) is a high altitude tramway line located in the Swiss canton of Valais near the resort of Zermatt.

The line included a station called Riffelalp, but this was situated some distance from the resort.

The original track was 480 metres (1,570 ft) long and electrified, using a twin overhead line carrying a three-phase ac supply at 550 volts.

At the resort end of the line, there is a terminal loop and a depot for the trams, with a battery station.

Both trams are powered by a battery (80 V, 400 Ah) and two d.c. motors each delivering 10 kW, and a maximum speed of 10 km/h (6.2 mph).

During the resort's winter season, from December to April, a snowmobile service is provided in place of the tram.
