Felix Thaddeus Mackiewicz (November 20, 1917 – December 20, 1993) was an American professional baseball player. An outfielder, he appeared in six Major League Baseball seasons for the Philadelphia Athletics from 1941 to 1943, the Cleveland Indians from 1945 to 1947, and the Washington Senators in 1947. The native of Chicago, Illinois, threw and batted right-handed. He stood 6 feet 2 inches (1.88 m) tall and weighed 195 pounds (88 kg).
Mackiewicz attended Purdue University, where he played college baseball for the Boilermakers from 1938–1940. He signed with the Athletics in 1940 and made his Major League debut in September 1941 after breaking into minor league baseball with the Class B Wilmington Blue Rocks. Mackiewicz spent 1941 and 1942 mostly with Wilmington, and played in 20 total games for the Athletics over three seasons. After being released by the Athletics a month into the 1943 season, he spent the rest of 1943 and all of 1944 with the Baltimore Orioles before being called up by the Cleveland Indians for 1945.
The 1945 and 1946 seasons were Mackiewicz' only full seasons in the Majors. In 1945, as the Indians' regular center fielder, he got into 120 games, made a career-high 98 hits, and slugged his only two Major League home runs. Mackiewicz was waived by the Indians two games into the 1947 season, and was picked up by the Washington Senators, ending his major league career with three games played for them. He spent three more seasons in the minor leagues before retiring.
