Charles Francis Sellman (January 21, 1851 – May 6, 1907) was an American professional baseball player.

In 1869, Sellman participated in the first professional pennant race for the Maryland club of Baltimore.

He was the regular shortstop, played in 19 of 27 games on record, and scored 42 runs, a little below the team average rate.

The Kekionga club of Fort Wayne, Indiana hired several Baltimore natives in order to compete in the first professional league, the 1871 NA.

Sellman played one game early in the 1875 season and never appeared in the National League that succeeded the NA the following year.
