Rogelio Lazaro Valdés Rojas (February 23, 1920 – December 3, 2005) was a Major League Baseball player.
Born in Havana, Cuba, Valdés was one of many who only appeared in the major leagues during World War II. His career consisted of one at bat as a pinch hitter for the Washington Senators at Fenway Park in Boston on May 3, 1944. He went 0-for-1 for a batting average of .000. He did not appear in the field, so his playing position is unknown.
Valdés died in Miami, Florida, at the age of 85.
