Carlos Humberto Caszely Garrido (born 5 July 1950 in Santiago, Chile) is a Chilean former footballer, nicknamed "Rey del metro cuadrado" (English: King of the square meter, Portuguese: O Rei do Metro Quadrado), who played as a forward.
Regarded as one of Chile's most important players, between 1969 and 1985, Caszely won 48 caps and scored 29 goals for the Chile national team, including participations in the 1974 and 1982 World Cups.
Cazsely played for several football teams in his career, including Colo-Colo (1968-1973), Levante UD (1973-1974), RCD Espanyol (1974-1978), finally returning to Colo-Colo (1978-1985). He ended his career with Barcelona SC in 1986.
During the opening 1974 FIFA World Cup match against West Germany, Caszely was given a red card by the match referee, Do?an Babacan, becoming the first player to be sent off in this manner. Red and yellow cards had already been introduced in the past World Cup (1970). In the 1982 World Cup he missed a penalty against Austria. In June 1976, Caszely played for the national team of Catalonia in a friendly against the Soviet Union, providing an assist to Johan Neeskens.
