In Jainism, Gautamswami (also known as Gautama Swami) was the chief disciple (ganadhara) of Lord Mahavira, the 24th Tirthankara. The Chyavan Tithi (Chyavan meaning "conception" or "embodiment") marks the day he entered his mother’s womb.

According to Jain tradition, Gautamswami’s Chyavan Tithi falls on the thirteenth day (Trayodashi) of the bright half (Shukla Paksha) of the month of Kartik in the Jain calendar. This day is observed with devotion, prayers, and sometimes special discourses in Jain temples.
