Hill 305 is a feature on Earth's Moon, a mountain in the Hadley-Apennine region. Astronauts David Scott and James Irwin landed the Lunar Module Falcon about 21 km southeast of it in 1971, on the Apollo 15 mission, but they did not visit it. They could see it on the northwestern horizon from nearly everywhere they went. The peak rises approximately 1300 meters above the surrounding plain, known as Palus Putredinis, and part of Hadley Rille curves along its southern margin.
