Boloria bellona, the meadow fritillary, is a North American butterfly in the brushfoot family, Nymphalidae.

The common name, meadow fritillary, is also used for a European butterfly species, Melitaea parthenoides.

The upperside of the wings is yellow orange with dark spots, lines, and zigzagged bands.

The meadow fritillary is frequently encountered in wet, open places, including pastures, fields and streamsides.

Females deposit greenish-yellow eggs near the host plant on twigs or leaves.
