Veronica prostrata, the prostrate speedwell or rock speedwell, is a species of flowering plant in the family Plantaginaceae, native to Europe. Growing to 10–15 cm (4–6 in) tall, it is a temperate semi-evergreen prostrate perennial plant. As it forms a mat of foliage, it is suitable for groundcover or in the alpine garden. Blue flowers are borne in summer, in terminal racemes above paired leaves.
