The Swedish Solar Telescope (or SST) is a 1 m telescope on La Palma in the Canary Islands. It is run by the Institute for Solar Physics of the Royal Swedish Academy of Sciences.

The SST is a vacuum telescope - meaning that it is evacuated internally to avoid disruption of the image from air inside. This is a particular problem with solar telescopes because of the heating from the large amounts of light collected being passed on to any air causing image degradation.

The SST superseded the SVST - the Swedish Vacuum Solar Telescope, which was 47.5cm in diameter.
