Samudrakotigambhira (समुद्रकोटिगम्भीर, IAST: Samudrakoṭigambhīra) is a Sanskrit-origin Hindu boy-name meaning “Profoundly deep as ten million oceans”. Joining samudra (ocean), koṭi, and gambhīra (deep, grave, unfathomable), this name honours Vishnu as one whose infinite depth of wisdom, mystery, and compassion surpasses ten million seas.

Meaning, etymology & significance

Samudra, the vast ocean, has always been a Vedic symbol of the boundless and the mysterious. Gambhīra carries a dual resonance — it means both physically deep and gravely dignified in character, pointing to Vishnu's unfathomable wisdom and equanimity. In the Purāṇas, Vishnu reclines upon the primordial ocean (kṣīrasāgara), and this epithet deepens that imagery: his essence is more profound than ten million such cosmic waters combined.

This epithet of Vishnu is particularly meaningful in Vaishnava philosophy, where his inscrutable nature (māyā) is likened to an ocean no jīva can fully sound. Pronunciation: sah-MUD-rah-KOH-tee-gam-BHEE-rah; gambhīra alone is sometimes given as a boy's name meaning 'deep, serious.'
