The St. Lucia wren is a very small passerine bird in the wren family Troglodytidae that is found on the Caribbean island of Saint Lucia. The name troglodytes means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the house wren, now renamed the northern house wren.
