Viswasam (transl. Allegiance) is the soundtrack album composed by D. Imman for the Indian Tamil-language action drama film of the same name directed by Siva, starring Ajith Kumar and Nayanthara in lead roles and produced by Sendhil Thyagarajan and Arjun Thyagarajan of Sathya Jyothi Films. The film was initially announced with Yuvan Shankar Raja as the composer, who left the project citing schedule conflicts and several other composers were rumoured to score music before the team approached Imman as the music director. This film marked Imman's first collaboration with Ajith Kumar and Siva.
