Frank George "Noodles" Hahn (April 29, 1879 – February 6, 1960) was an American starting pitcher in Major League Baseball who played for the Cincinnati Reds and New York Highlanders between 1899 and 1906.

He lacked the blazing speed of a Grove or a Rube Waddell, but he could tie up batters into more knots than 10 sailors could untie in a week.

Hahn had given up beer and liquor over the winter and said that he felt good going into the season, but he entertained the possibility that the coming year could be his last.

Hahn planned to finish school the next winter and had thoughts of completing postgraduate work and taking a trip to Germany before beginning veterinary practice.

[13] During the 1905 season, Cincinnati manager Joe Kelley announced that the team was searching for a left-handed pitcher who could replace Hahn.

Kelley said, "While we have not lost confidence in Hahn, we realize that he can't last forever... he has already passed the limit that usually is fixed for southpaws in fast company, about five or six years at the most.

[15] An Ohio newspaper issued an article in July 1908 stating that Hahn had pitched well in semipro baseball and that he would soon be back with the Reds.

[16] In 1909, another newspaper report indicated that Hahn had sought medical attention for the arm issue and that he would attempt a major league comeback.

[17] By 1910, Hahn was giving private instruction to pitching prospect Rube Benton, who Cincinnati had signed to a $6,000 contract.
