Charles William Chech (April 27, 1878 – January 31, 1938) was a pitcher who played in Major League Baseball between 1905 and 1909.

His most productive season came in his rookie year for Cincinnati, when he recorded career-highs in wins (14), strikeouts (79), starts (25), complete games (20) and innings pitched 2672⁄3, while posting a 2.89 ERA.

After going 11–7 for Cleveland, he was sent to the Red Sox with Jack Ryan in the same trade that brought Cy Young to Boston.

[1] Returning to Saint Paul, the 1910 U.S. Census shows Chech had become a druggist, supporting his wife and his widowed mother-in-law.

Chech married secondly to Catherine M Tierney on 29 Nov 1918 in Los Angeles County, California.
