Vaidalavrtraghna (वैदलवृत्रघ्न, IAST: Vaidalavṛtraghna) is a Sanskrit-origin Hindu boy-name meaning “Slayer of the Vṛtra associated with Vaidala”. From vaidala (possibly relating to a specific demon or context, perhaps 'of the Vidala lineage'), vṛtra (the great Vedic serpentine demon of obstruction), and ghna (slayer), this name attributes to Vishnu the destruction of a Vṛtra-like obstruction in a Vaidala context, celebrating His role as remover of cosmic blockages.

Meaning, etymology & significance

Vṛtra is among the most ancient adversaries in Vedic cosmology, the demon of drought and obstruction slain by Indra — but in the Purāṇic synthesis, Vishnu's power underlies all such victories. The qualifier vaidala may refer to a specific story, lineage, or epithet of the particular demon destroyed, grounding the epithet in a concrete narrative. The name thus joins Vishnu's timeless function as cosmic liberator to a specific act of grace.

This name of Vishnu is found in the Sahasranāma's extended narrative section and is used in scholarly and liturgical contexts. The name Vṛtraghna alone has historical usage as an epithet; the compound is rare as a personal name and warrants further research.
