Asid pantotenik, juga dipanggil pantotenat atau vitamin B₅ (sejenis vitamin B), ialah sejenis vitamin larut-air. Bagi kebanyakan haiwan, asid pantotenik ialah suatu nutrien perlu. Ia diperlukan bagi mensintesis koenzim A (CoA), selain daripada mensintesis dan memetabolismekan protein, karbohidrat dan lemak.

Asid pantotenik ditemui oleh Roger J. Williams pada 1933.^[2]
