The Seerenbach Falls (German: Seerenbachfälle) are a cascading set of three waterfalls east of Betlis in the municipality of Amden (canton of St. Gallen, Switzerland). The waterfalls form a creek, the Seerenbach (lit. 'Seeren Creek'), which drains into Lake Walen (Walensee). The Rinquelle (English: Rin Spring) joins the lowest of the Seerenbach Falls, creating a fourth one (English: Rinquelle Falls or German: Rinquellenfall).

The waterfalls are numbered Seerenbach Falls I, II and III from top to bottom. The upper cascade has a height of 50 m (160 ft), the middle one of 305 m (1,001 ft), and the lower one of 190 m (620 ft), for a total of 585 m (1,919 ft). Seerenbach Falls II are the second-highest waterfall in Switzerland, after the Mürrenbach Fall (417 m (1,368 ft)). The waterfalls are a popular site on the hiking trail from Weesen to Quinten.

The Rinquelle is a karst spring that joins Seerenbach Fall III in the Seerenbach canyon. Behind it, there is a river cave system that was explored between 1953 and 1981. The waterfall of the Rinquelle is 48 m (157 ft) high.
