William Kwong Yu Yeung (also known simply as Bill Yeung) (Chinese: 楊光宇) is a Hong Kong-born, Canadian amateur astronomer with telescopes based in the United States.[1]

He is a prolific discoverer of asteroids and also discovered the comet 172P/Yeung. He also discovered the object J002E3, which was first thought to be an asteroid, but is now known to be part of a Saturn V Rocket that propelled Apollo 12 into space. He worked first from Rock Finder Observatory (IAU code 652) in Calgary, Alberta, and now works from Arizona's Desert Beaver Observatory (IAU code 919) and Desert Eagle Observatory (IAU code 333).
