Bhishmaka (Sanskrit: भीष्मक, romanized: Bhīshmaka), also called Hiranyaroman,[1] is the king of Vidarbha In Hinduism.

At the time of the birth of Rukmini, the text describes a celestial voice instructing him to marry his daughter to a four-armed one (Caturbhujā) who had been born on earth.

After eight years, he betroths his daughter to Shishupala upon the insistence of the latter's father, Damaghosha, who tells him that Caturbhujā was an epithet of his son.

[6] In the Harivamsha, when the king Bhishmaka's eldest son Rukmi chooses to marry his sister Rukmini off to suitors through a svayamvara ceremony, the king opposes Rukmi's decision, regarding it to be bad conduct on his part.

When the king grants an audience to Krishna, he begs the god's forgiveness for this folly, upon which the latter agrees with his opinion, revealing that the bride was in fact Lakshmi, the goddess of prosperity.
