Héctor Anibal Maestri Garcia (April 19, 1935 – February 21, 2014) was a Cuban-born Major League Baseball pitcher.

Maestri was one of nine ballplayers to have appeared for both of the 20th century, American League Washington Senators franchises, and one of only three to have played for them in consecutive seasons.

His lone appearance for the earlier Senators, during their final days in the U.S. capital, saw him hurl two scoreless innings of relief against the Baltimore Orioles on September 24, 1960, at Griffith Stadium.

Almost a full year later, on September 17, 1961, he appeared in his second and last MLB game for the expansion Washington club, starting and pitching six innings against the Kansas City Athletics, also at Griffith Stadium.

Maestri's two-game career totals were 81⁄3 innings pitched, seven hits and three bases on balls allowed, three strikeouts, a 0–1 record, and a 1.13 ERA.
