Vishvaksena or Vishwaksena, also known as Senai Mudalvar (Sena Mudaliar) and Senadhipathi (all literally army-chief), is the commander-in-chief of the army of the Hindu god Vishnu and the gate-keeper and chamberlain of Vishnu's abode Vaikuntha. Vishvaksena is worshipped before any ritual or function in Vaikhanasas and Sri Vaishnavism sects. He occupies an important place in Vaikhanasa and Pancaratra temple traditions, where often temple festivals begin with his worship and procession.
