To Ngoc Van is a pit-floored crater on Mercury, named after the Vietnamese artist Tô Ngọc Vân.

[2] Its floor displays an irregularly shaped collapse feature, which is called a central pit.

[2] Such a feature may have resulted from collapse of a magma chamber underlying the central part of the crater.

[2] To the southeast of To Ngoc Van is Bruegel crater, and to the northwest is Burns.

To the northeast is a large (329 km diameter), unnamed crater of Tolstojan in age.
