Historically the municipality was named "Torrelodones" (Lodones' Tower). That name led to the current name of the town Torrelodones. The name comes from, for one side, the Muslim watchtower that Muslims used during Al-andalus age to guard the city from the attacks of Christian people during the Iberian peninsula's reconquest. For the other side, "Lodon" (hack berry) is a type of tree that was really abundant in that zone whose scientific name is Celtis australis.
