Thymus pulegioides (common names broad-leaved thyme, lemon thyme) is a species of flowering plant in the family Lamiaceae, native to Europe. Growing to 5–25 cm (2–10 in) tall by 25 cm (10 in) wide, it is a small spreading subshrub with strongly aromatic leaves, and lilac pink flowers in early summer. The specific epithet pulegioides highlights its similarity to another species within Lamiaceae, Mentha pulegium (pennyroyal).
