Galanthus reginae-olgae, Queen Olga's snowdrop,[6] is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans (parts of Greece and the former Yugoslavia).

It is cultivated as ornamental bulbous plant, preferring warmer situations in the garden than other species of Galanthus (snowdrops).

Galanthus reginae-olgae has revolute leaves that are dark green with a central silver line and when fully grown are 11–15 cm long by 3–8 mm wide.

Populations of Galanthus reginae-olgae that flower at different times, with or without the leaves being fully developed, have been described as separate species or subspecies.

[8] The cultivar 'Cambridge', originating from the Cambridge University Botanic Garden, has large green markings on the inner tepals.
