Luis Aloma Barba (July 23, 1923 – April 7, 1996), nicknamed "Witto", was a relief pitcher in Major League Baseball who played for the Chicago White Sox from 1950 through 1953. Aloma batted and threw right-handed. He was born in Havana, Cuba. He would also pitch in farm systems for the Washington Senators and the Detroit Tigers.
In 1944 Aloma signed as an amateur free agent with the Washington Senators. In 1944 he split time between the Class D Kingsport Cherokees of the Appalachian League and the Class A-1 Chattanooga Lookouts of the Southern Association. He went a combined 8–7 with a 4.68 ERA in 26 games, eight for starts.

In 1947 Aloma split the season between the Lookouts and the Class B Charlotte Hornets of the Tri-State League. He had a dismal stint with the Lookouts, going 2–4 with a 6.93 ERA in 15 games. With the Hornets on the other hand he was quite impressive, going 8–7 with a 3.62 ERA in 18 games. He finished a combined 10–11 with a 4.74 ERA in 33 games.
He spent his last year in the Senators' farm system playing for his home town team, Havana Cubans of the Florida International League. In what would turn out to be his best professional season at any level he went 19–6 with a 1.77 ERA in 28 games.
In 1949 he was traded from Washington to the Detroit Tigers.
He spent the 1949 season with the Triple-A Buffalo Bisons of the International League. He compiled a 10–9 record with a 4.60 ERA in 38 games, 22 for start. This would be his only season in the Tigers' system.
Aloma was again traded, this time on August 5, 1949 from the Tigers to Chicago White Sox for Alex Carrasquel. He didn't pitch in the minors for the rest of the 1949 season.
