Víctor José Davalillo Romero (31 July 1939 – 6 December 2023) was a Venezuelan professional baseball player. He played in Major League Baseball (MLB) and the Mexican League as an outfielder from 1963 to 1982.

Davalillo (pronounced da-va-LEE-yo) played in Major League Baseball (MLB) for the Cleveland Indians (1963–68), California Angels (1968–69), St. Louis Cardinals (1969–70), Pittsburgh Pirates (1971–73), Oakland Athletics (1973–74), and Los Angeles Dodgers (1977–80) as an outfielder.

Davalillo, who batted and threw left-handed, was a leadoff hitter known for his speedy baserunning and capable defense. He was a fan favorite during his years with the Indians, and became a valuable utility player later in his career. He was also recognized as a superb pinch hitter.

Davalillo also had an exceptional career in the Venezuelan Winter League, where he is the all-time leader in total base hits and career batting average. He played for 30 years in the U.S., Mexico, and his homeland, compiling more than 4,100 base hits total.

Although many baseball references show Davalillo's birthplace as Cabimas, Venezuela, in 2006 he told a biographer that he was born in Churuguara, Falcón on 31 July 1939. Other sources have given his date of birth as 30 July 1939, or sometime in 1936. His family moved to Cabimas a few days after he was born. He grew up in the Costa Oriental region on Lake Maracaibo. His older brother, Pompeyo Davalillo, played briefly for the Washington Senators in 1953.

Davalillo began his career as a pitcher. He signed a contract as an amateur free agent with the Cincinnati Reds in 1958. He was sold to the Indians organisation in 1961 and moved up the ladder to Jacksonville, their Triple-A club in the International League. Davalillo won the first batting title in the Jacksonville Suns history with a .346 batting average in 1962.

Davalillo became the eighth Venezuelan to play in Major League Baseball when he joined the Indians in 1963 as their leadoff hitter and center fielder. By mid-June, he was hitting for a .304 batting average and was receiving consideration for the American League Rookie of the Year Award when, he was hit by a pitch by Hank Aguirre and suffered a broken wrist. He returned from the injury to lead the Indians in hitting with a .292 along with a career-high 7 home runs in 90 games however, after the injury, he was never the same hitter against left handed pitching. In October, he was named to the 1963 Topps All-Star Rookie Team. The following season, Davalillo finished second in the league in fielding percentage among center fielders and was named as a recipient of the 1964 American League Gold Glove Award. He was the first left-handed throwing outfielder to win an American League Gold Glove Award (Vada Pinson won the 1961 National League Gold Glove Award as a left-handed outfielder).

In 1965, Davalillo led the league in batting at mid-season with a .345 batting average, earning him a place as the starting center fielder for the American League team in the 1965 All-Star Game. He ended the 1965 season with a .301 batting average, third-best in the American League behind Tony Oliva and Carl Yastrzemski, the only other players to break the .300 mark that year. Davalillo had an off year in 1966, and the Indians began to use him in a platoon role, playing him when they faced right-handed pitchers. In 1967, he hit for a .302 average against right-handed pitchers but, only managed a .188 average against left handers, for a .287 average overall.
