Tampichthys is a genus of cyprinid fish endemic to east–central Mexico.

[1][2] They are entirely restricted to the Pánuco River basin, except T. ipni which also occurs in some other Mexican rivers that drain into the Gulf of Mexico.

[2] These are small fish, generally no more than 9 cm (3.5 in) long,[1] and overall brownish-silvery with a distinct dark horizontal line from the head to the tail base.

[2] Tampichthys was formerly considered a part of Dionda instead of a separate genus.
