Robert Kitridge Wicker (May 25, 1877 – January 22, 1955) was an American professional baseball player who was a pitcher in the Major Leagues from 1901 to 1906.

He would play for the St. Louis Cardinals, Chicago Cubs, and Cincinnati Reds.

In early 1903, he was traded to the Cubs, where he won 20 games for the only time in the majors.

However, he started off slow in 1906 and was traded to the Reds, thus missing out on the Cubs' pennant win.
