The Vasu Doorjamb Inscription is an early 1st-century CE Sanskrit inscription in Brahmi script dedicated to the deity Vāsudeva, related to the Vaishnavism tradition of Hinduism. It is also one of the several dedicatory inscriptions from Mathura bearing the name of the Indo-Scythian Northern Satrap ruler Sodasa, which are useful as historic markers for the first half of the 1st century CE. The Vasu Doorjamb Inscription is another archaeological evidence about ancient Vaishnavism, providing another link about the continuity between ancient religious traditions and contemporary Hinduism.
