Roy Maxwell Alvis (born February 2, 1938) is an American former professional baseball player. He played in Major League Baseball as a third baseman from 1962 through 1970, most notably for the Cleveland Indians where he became a two-time All-Star. He played his final season with the Milwaukee Brewers.

Alvis was born in Jasper, Texas, and graduated from Jasper High School (Jasper, Texas). He attended the University of Texas at Austin.^[1]

Alvis was signed by the Cleveland Indians as an amateur free agent in 1958. He played his first major league game on September 11, 1962, with the Cleveland Indians.^[2]

Alvis became the everyday third baseman for the Indians in 1963. He enjoyed single-season career-high numbers in batting average (.274), RBI (67), runs (81), hits (165), doubles (32) and triples (7). He added 22 home runs (also a personal high), and appeared to be on his way to stardom, but a bout with spinal meningitis disabled him for six weeks in 1964 (a season in which he hit 18 homers in only 381 at-bats).

Alvis made a remarkable comeback in 1965, hitting 21 home runs, and was rewarded by being selected for the All-Star game, representing the American League. He turned in a solid 18 HR performance in 1966 and led the team with 21 in 1967. His batting average fell to .223 as a full-time player in 1968, and he was relegated to spot duty with Cleveland in 1969, appearing in only 66 games.

He was traded along with Russ Snyder from the Indians to the Brewers for Roy Foster, Frank Coggins and cash during spring training on April 4, 1970.^[3] As a backup in Milwaukee, he hit .183 with three homers in 62 games, being released at the end of the season.
