Vishvaketu (विश्वकेतु, IAST: Viśvaketu) is a Sanskrit-origin Hindu boy-name meaning “Whose banner encompasses the entire universe”. From 'viśva' (all, universe) and 'ketu' (banner, sign, ray of light), Viśvaketu proclaims Viṣṇu as the universal standard-bearer whose glory illumines all creation.

Meaning, etymology & significance

The word 'ketu' in Sanskrit carries the meanings of a banner or flag, a comet, and also a ray of light—all pointing to visibility, brilliance, and proclamation. Combined with 'viśva,' the name declares that Viṣṇu's glory is the standard unfurled across the entire cosmos, recognizable to all conscious beings. This name connects to Viṣṇu's iconography, where his emblems (the lotus, conch, discus, and mace) serve as cosmic banners announcing divine presence.

Viśvaketu is a dignified name borne by Viṣṇu in his role as the cosmic overlord whose presence pervades and marks every corner of existence. It is pronounced vish-va-ke-tu, with clear separation of its two root components.
