The municipality (originally the parish) is named after the old Røyken farm (Norse Raukvin), since the first church was built there. The first element is raukr which means "pile, stack; mountain" and the last element is vin which means "meadow" or "pasture".

The coat-of-arms is from modern times. They were granted on 15 December 1967. The figure shows a yellow fire on a blue background. It was chosen as a semi-canting symbol to represent smoke (which cannot be depicted in heraldry). The background for the motif is a common misunderstanding of the name as røyken the definite form of røyk meaning "smoke". style="float: center;" Number of minorities (1st and 2nd generation) in Røyken by country of origin in 2017 • Ancestry — Number • Poland — 829 • Lithuania — 253 • Sweden — 216 • Germany — 172 • Denmark — 164 • India — 113 • Pakistan — 109 • Afghanistan — 104 • 96 • Iran — 85
