Dilly is a crater in the Elysium quadrangle of Mars, located at 13.24° North and 202.9° West. It is only 1.3 km in diameter and was named after Dilly, a town in Mali.[1]

Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak.[2] The peak is caused by a rebound of the crater floor following the impact.[3]
