Otto Adam Neu (September 24, 1894 – September 19, 1932) was a shortstop who played briefly in Major League Baseball during the 1917 season. Listed at 5 ft 11 in (1.80 m), 170 lb., Neu batted and threw right-handed. He was born in Springfield, Ohio.

Neu was a major leaguer whose career, statistically speaking, was similar to that of Moonlight Graham. Previously, he had played minor league baseball for the Senators, Indians and Browns organizations, and made his majors debut on July 10, 1917 with the Browns, appearing for them in a game against the Yankees at Sportsman's Park.

But Neu did not have a fielding chance or turn at-bat, and never appeared in a major league game again. Following his playing retirement he worked as a salesman.

Neu died of intestinal influenza in Kenton, Ohio, five days short of his 38th birthday.
