Edward Richard Doheny (November 24, 1873 – December 29, 1916) was an American pitcher in Major League Baseball (MLB).

He started his professional baseball career with the New York Giants of the National League (NL) in 1895.

He signed with the team in September, and that year, he had a win–loss record of 0–3 and a 6.66 earned run average (ERA).

He pitched well and ended the season with a record of 16–8 and a 3.19 ERA, helping the Pirates win the NL championship.

Doheny continued to suffer from paranoid delusions, and on September 22, his brother took him back home to Andover.

Doheny's condition did not improve and was worsened after he read about the Pirates' fourth loss in the 1903 World Series.

Early the next morning, Doheny attacked Howarth with a cast-iron stove leg and knocked him unconscious.
