Daniel Michael McGinn (born November 29, 1943) is an American former professional baseball player, a former left-handed pitcher in Major League Baseball (MLB). He was drafted by the Cincinnati Reds in the 1st round (10th pick) of the 1966 amateur draft (Secondary Phase), and later drafted by the Montreal Expos from the Reds as the 27th pick in the 1968 expansion draft. He played for the Reds (1968), Expos (1969-1971), and Chicago Cubs (1972).

McGinn hit the first home run in Montreal Expos history. It took place at Shea Stadium in their first game on April 8, 1969. McGinn came to bat in the top of the 4th and launched a solo shot against Tom Seaver, it bounced off the top of the wall in right field and went over. Six days later he earned the win with 51⁄₃ innings of shutout relief as Montreal defeated the St. Louis Cardinals 8-7. During his career, he gave up 225 walks in 408.2 innings, for a BB/9IP of 4.95, much higher than the National League average at that time. However, with 293 strikeouts, his K/9IP was 6.45, which was higher than the National League average.
