Södra Sytertoppen, Mountain summit in Västerbotten County, Sweden.

Södra Sytertoppen rises 1,685 metres above sea level in the Norra Storfjället massif, in the northernmost corner of Västerbotten county inside the Vindelfjällen nature reserve. It is the highest point of the massif's southern part, separated from Norra Sytertoppen by the east-west Syterskalet valley. Its northern face drops steeply into that U-shaped valley, and the summit plateau is covered with kilometre-long fields of loose stones and many cairns built by visitors.

Södra Sytertoppen lies in Norra Storfjället, in the northernmost corner of Västerbotten County in Lappland, within the Vindelfjällen nature reserve, one of Europe's largest protected areas. The reserve has been proposed as a new Swedish national park, but no decision has been taken. The summit reaches 1,685 metres, making it the third-highest peak in Västerbotten County after Norra Sytertoppen and Måskostjakke.

The Sami name Syjhterentjåhke appears alongside the Swedish name, and the summit itself is covered with many stone cairns piled up by visitors. Photographer Claes Grundsten has remarked that their number makes the place seem like a ritual object.

The easiest ascent starts from the west, gaining about 800 metres of height; halfway up a ravine opens to the left above Västra Syterbäcken. The upper terrain is kilometres of loose stone fields, and in poor weather with a low cloud base the wide plateaus edged by steep sections make route-finding hard. The northern side drops into the U-shaped Syterskalet valley.
