Luis Rolando Arrojo Avila (born July 18, 1965) is a retired Major League Baseball pitcher who pitched from 1998 to 2002.

Arrojo made his mark with the teams from Villa Clara in the Cuban National Series, where he still is the all-time leader in hit batsmen.

However, in 1999, with teams and hitters more familiar with him and with his developing health problems (as critics claimed, these health problems were due to a lack of conditioning by Arrojo and his refusal to listen to coaches), Arrojo's numbers began to deteriorate, and he showed signs of inability to get left-handed hitters out.

After the season, the Devil Rays traded him to the Colorado Rockies with Aaron Ledesma for Vinny Castilla.

He was not re-signed after the 2002 season and finished his career with four appearances for the New York Yankees' Triple-A affiliate in Columbus in 2003.
