Nanki-Katsuura Onsen (南紀勝浦温泉) is a coastal onsen, or hot spring, located in Nachikatsuura, Wakayama Prefecture, Japan. Originally known as "Katsuura Onsen", the "Nanki-" was added to distinguish it from another onsen in Katsuura, Chiba.

Known as the "Matsushima of Kii", Nanki-Katsuura Onsen is one of the most popular hot springs in Japan due to its location along the coast and springs within caves. The spring is listed as the "Top 100 Onsens" by Kankokeizai News.
