Budhagupta (Sanskrit: बुधगुप्त) (reigned c. 476–495) was a Gupta emperor. He was the successor of Kumaragupta II and the predecessor of Narasimhagupta Baladitya. He was the son of Purugupta. He had close ties with the rulers of Kannauj kingdom and together they sought to rule the Huns out of the fertile plains of Northern India.
The Damodarpur copper-plate inscription informs us that Pundravardhana bhukti (the present-day North Bengal) was ruled by his two viceroys (Uparika Mahararaja) Brahmadatta and Jayadatta. The Eran stone pillar inscription of two brothers, Matrivishnu and Dhanyavishnu mentions Budhagupta as their emperor (Bhupati), under whom Maharaja Surashmichandra was governing the land between the Yamuna and the Narmada The Buddha image inscription found from Mathura is dated in Budhagupta's reign. It shows that his authority was extended to Mathura in the north.

Burt in 1838.
Eran Stone Pillar Inscription of Budhagupta (484-485 CE)
Victorious is the lord, the four-armed (god Vishnu)— whose couch is the broad waters of the four oceans; who is the cause of the continuance, the production, and the destruction, &c., of the universe; (and) whose ensign is Garuda! (Line 2.)— In a century of years, increased by sixty-five; and while Budhagupta (is) king; on the twelfth lunar day of the bright fortnight of the month Âshâdha; on the day of Suraguru; (or in figures) the year 100 (and) 60 (and) 5:— (L. 3.)— And while Surashmichandra is governing, with the qualities of a regent of one of the quarters of the world, (the country that lies) between the (rivers) Kâlindi and Narmadâ, (and) is enjoying in the world the glory of (being) a Mahârâja;— (L. 4.)— On this (lunar day), (specified) as above by the year and month and day; — by the Mahârâja Mâtrivishnu, who is excessively devoted to the Divine One; who, by the will of (the god) Vidhâtri, was approached (in marriage-choice) by the goddess of sovereignty, as if by a maiden choosing (him) of her own accord (to be hey husband); whose fame extends up to the borders of the four oceans; who is possessed of unimpaired honour and wealth; (and) who has been victorious in battle against many enemies;—who is the son of the son's son of Indravishnu, who was attentive to his duties; who celebrated sacrifices; who practised private study (of the scriptures); who was a Brâhman saint; (and) who was the most excellent (of the followers) of the Maitrâyanîya (sâkhâ);— who is the son's son of Varunavishnu, who imitated the virtuous qualities of (his) father;— (and) who is the son of Harivishnu, who was the counterpart of (his) father in meritorious qualities, (and) was the cause of the advancement of his race;— (L. 8.)— (By him) and by his younger brother Dhanyavishnu, who is obedient to him, (and) has been accepted with favour by him,— this flag-staff of the divine (god) Janârdana, the troubler of the demons, has been erected, for the purpose of increasing the religious merit of (their) parents. (L. 9.)— Let prosperity attend all the subjects, headed by the cows and the Brâhmans!
