Masashi Hirose is a veteran Japanese voice actor whose long career includes voicing Riku Doldo III in One Piece before health issues forced a recast in 2014.

Based in Osaka Prefecture, Hirose has worked in anime dubbing since the 1970s and is affiliated with the agency Production Baobab. He is best remembered for voicing Ramba Ral in the original Mobile Suit Gundam, the wrestler Rikishiman on Kinnikuman, the villain Gosterro in the mecha series Blue Comet SPT Layzner, and teacher Nakano-sensei on Lovely Complex. His 2014 hospitalization also led to Katsuhisa Hōki taking over his part in Gundam Build Fighters Try.
