Thomas Alan Grieve (born March 4, 1948) is a former Major League Baseball player. He played from 1970–79 for the Washington Senators, Texas Rangers, New York Mets and St. Louis Cardinals. Nicknamed "TAG", which are his initials, Grieve's best season was 1976 with the Rangers when he hit .255, belted 20 home runs and had 81 runs batted in.

On December 8, 1977, he was involved in a rare four-team trade that involved the New York Mets, Atlanta Braves, Pittsburgh Pirates and the Texas Rangers. Grieve and a player to be named later (Ken Henderson) were sent to the Mets, who also received Willie Montañez from the Braves. Texas sent Adrian Devine, Tommy Boggs and Eddie Miller to Atlanta and Bert Blyleven to the Pirates. The Pirates sent Al Oliver and Nelson Norman to the Rangers, who also got Jon Matlack from the Mets. Finally, the Mets sent John Milner to the Pirates.

Primarily an outfielder and a designated hitter, the right-handed batter finished his career with a .249 average, 65 homers and 254 RBIs in 670 games.

In between, Grieve posted five solid seasons in the Venezuelan Winter League while playing for the Águilas del Zulia, Leones del Caracas and Tiburones de La Guaira clubs between 1971 and 1979.
