Gardner is a small lunar impact crater in the northeast part of the Moon and is named after an American physicist Irvine Clifton Gardner. It lies due east of the crater Vitruvius (45 km distance), in a section of rough terrain north of the Mare Tranquillitatis. This crater was previously designated Vitruvius A before being given its present name by the IAU. Less than 35 km northeast of Gardner is the larger crater Maraldi.

Its diameter is 18 km and being about 3,000 meters deep. The area is less than 250 km² and its perimeter is over 50 km.

It is a circular crater with sloping inner walls and an interior floor that occupies about half the total crater diameter. The southern half of the floor has a slight rise before reaching the inner wall. The crater is not significantly eroded, and the outer rim is relatively sharp and well-defined. The most distinctive feature is a row of four rounded hills along the northern floor of the crater.

To the south is an elevated area unofficially known as the "Gardner megadome", it consists of nearby other satellite craters including Vitruvius B, H and T and Maraldi D.
