John G. Otten (August 21, 1870 – October 17, 1905) was a catcher for the St. Louis Browns of the National League in 1895.

An injury in the catching position led manager Joe Quinn of the St. Louis Browns to get on the wire to bring Otten into the majors.

However, his major league career would only last a few games due to an injury suffered on July 7 on a pitch taken to his thumb while attempting a bunt.

It affected his ability to catch runners behind the plate and it would continue to hinder for the rest of his playing days.
