Viola riviniana, the common dog-violet, is a species of flowering plant in the family Violaceae, native to Eurasia and Africa. It is also called wood violet and dog violet. It inhabits woodland edges, grassland and shady hedge banks. It is found in all soils except those which are acid or very wet.

Growing to 10 cm (3.9 in) tall and 50 cm (20 in) broad, this prostrate perennial has dark green, heart-shaped leaves and produces multiple violet coloured flowers in May and June.

Viola riviniana was voted the county flower of Lincolnshire in 2002, following a poll by the wild plant conservation charity Plantlife.

It is the food plant of the pearl bordered fritillary, small pearl-bordered fritillary, silver-washed fritillary and high brown fritillary butterflies.
