Masayoshi Urabe (浦邊 雅祥? Urabe Masayoshi, born 1965) is a Japanese musician, best known for his intensely physical style of free improvisation on the alto saxophone and his deployment of long, laden silences. He has sometimes been compared to the late Japanese free jazz altoist Kaoru Abe.
He has played with many underground musicians in Japan, including Chie Mukai (Ché-SHIZU), Kan Mikami (Sanjah), Hiroshi Hasegawa (Astro, C.C.C.C.), Junko (Hijokaidan) and the psychedelic rock group Kousokuya. Recently he formed the group Sanjah, with folk singer Kan Mikami and drummer Toshi Ishizuka. He also performs with the Paris-based dancer Yukiko Nakamura.
