Star Musketeer Bismark (星銃士ビスマルク, Sei Jūshi Bisumaruku), also known as simply Bismark, is a Japanese anime television series created by Studio Pierrot.

The series aired on Nippon TV and its affiliates from October 7, 1984 to September 25, 1985, totaling 51 episodes. In 1986, the rights to Bismark were sold to the United States company World Events Productions (WEP). WEP reorganized and rewrote the series, incorporating most of the original episodes and creating six new ones before releasing it under the name Saber Rider and the Star Sheriffs.
