William D. Venable (born October 29, 1982 in Greenbrae, California) is a Major League baseball center fielder for the San Diego Padres. In the 2005 Major League Baseball Draft, he was selected by the Padres in the seventh round. Venable made his Major League debut on August 29, 2008, taking on the Colorado Rockies. In that game, he had four at-bats, collecting his first hit.

He is the son of former Major League outfielder Max Venable. He also played basketball for Princeton University, as well as San Rafael High School. He is the twenty-fifth Princeton alumnus to play in the Major Leagues, but he is the first African-American alumnus. He was the second athlete to earn first-team All-Ivy League honors in both baseball and basketball.

Venable was born in 1982 in Marin County, California at a time when his father Max was a Major League Baseball player for the nearby San Francisco Giants. He grew up travelling around the country with his father and also lived in Japan and the Dominican Republic. In high school, he envisioned himself as more likely to be a professional basketball player than baseball player. As both a high school sophomore and a high school junior, Venable was second-team All-Metro basketball player for the San Francisco Bay Area. He was the Marin County Athletic League (MCAL) most valuable player in basketball as a freshman, sophomore and junior. As a sophomore, he led his team to the MCAL League Championship. As a senior, he gave up the responsibility of being point forward.
