St. John is an eroded lunar impact crater on the Moon's far side. This crater is situated to the northeast of the huge Mendeleev walled plain, and southwest of Kohlschütter crater. To the east of St. John is the small Mills crater.

This is a heavily worn and eroded crater formation that is now little more than an uneven depression in the surface. It is scarcely distinguishable from the surrounding terrain, except from the shadows cast by the outer rim. The interior floor is uneven and marked by a chain of three small craterlets near the mid-point.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to St. John crater.
