Vellayambalam is a prominent junction in the city of Thiruvananthapuram in the state of Kerala, India. It is situated on the Rajapatha (Royal Path) that stretches from Kowdiar to East Fort. This junction connects the arterial roads connecting Kowdiar, Sasthamangalam, East Fort, Thycaud and Thampanoor. A statue of Ayyankali is situated in the centre of the roundabout which serves as a memorial to the freedom fighter.
The road leading from Kowdiar Square to the Fine Arts college via Vellayambalam junction, Museum and Rama Rao Lamp was constructed during the early 1930s and "Charalkonna" (Copper Pod tree) brought from Sri Lanka was planted as avenue trees. Before the widening, Vellayambalam junction was a tiny place, where four narrow roads met. A Wayside Inn (Vazhiambalam) of the revenue department occupied the south east corner of that junction at the foot of the diamond hill. As the Maharajah often passed through that junction, the inn was kept clean and whitewashed. Because of that white wayside inn (Vella Vazhi Ambalam ) that junction came to be known as 'Vellayambalam' (shortened form of Vella Vazhi Ambalam) and in due course the locality around was also named Vellayambalam.
