Nymphalis vaualbum or N. l-album, the Compton tortoiseshell,[1][3][4] or false comma, is a species of butterfly in the family Nymphalidae.

Thus vaualbum can be considered nomen nudum, giving Nymphalis l-album priority.

Regardless of the ground colour (grey-brown or a buff brown), there is great contrast between the dark chocolate-brown discal region and the paler postdiscal area in males, less so in females.

The subspecies, N. v. j-album's, range consists of Alaska and Canada south into Montana and Wyoming.

The species is also found in the Palearctic - Eastern Europe, Romania, Ukraine, the south of Russia to the areas west of the Urals, the southern part of Siberia to the Himalayas and Japan.
