Myosotis is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek μυοσωτίς "mouse's ear", which the foliage is thought to resemble. In the Northern Hemisphere, they are colloquially known as forget-me-nots or scorpion grasses. Myosotis alpestris is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are not to be confused with Chatham Islands' forget-me-nots, which belong to the related genus Myosotidium.
