Vali (Sanskrit: वाली) also known as Bali, was a vanara and the king of Kishkindha in the Hindu epic Ramayana. He was the son of Indra, the husband of Tara, the elder brother of Sugriva, and the father of Angada through his wife, Tara.

Vali obtained a pendant from his father, Indra, that which allowed him to restore his energy even when nearing death, making him a formidable fighter. He banished his brother Sugriva, who had assumed his throne, believing him to be dead. Sugriva sought the assistance of Rama, an avatar of Vishnu, to intervene in their conflict. During a duel between the brothers, Rama shot Vali in the chest with an arrow.

According to the epic, fourteen types of gems or treasures were produced from the churning of the ocean during the time of the Kurma avatar. Among these treasures were various apsaras (divine nymphs), one of whom was Tara. Tara was produced from the churning of the ocean, and Vali, who was assisting his father Indra in the churning, took Tara and married her.^{[citation needed]}

Vali was courageous, as shown when Tara tried to stop him and begged him not to fight Sugriva, warning that Rama was aiding Sugriva. Vali replied to Tara that, even if he were to face a god in battle, he could not ignore a challenge and remain silent. He added that even if the challenger had been his own son, Angada, or Sugriva's wife, Ruma, he would still accept the fight.

According to the Ramayana, a fierce asura named Mayavi came to the gates of Kishkindha and challenged Vali to a fight. Vali accepted the challenge, but as he approached, the asura grew terrified and fled into a cave. Vali entered the cave, instructing Sugriva to wait outside. When Vali didn’t return, and Sugriva saw blood oozing from the cave, he mistakenly concluded that Vali had been killed. Sugriva then sealed the cave with a large boulder and assumed the kingship of Kishkindha. However, inside the cave, Vali had defeated and killed the demon and soon returned home. Seeing Sugriva acting as king, Vali believed his brother had betrayed him. Though Sugriva tried to explain his actions, Vali refused to listen, forcing Sugriva to flee to Rishyamuka Mountain, the only place Vali couldn’t enter due to a curse from the sage Matanga.

Vali was granted a golden pendant by his father, Indra. According to the Valmiki Ramayana, the pendant significantly increased Vali's energy during combat.

Vali wore the powerful pendant given to him by his father, Indra, during his battle with the demon Dhundubhi and defeated him. The Valmiki Ramayana also describes Vali as having great strength, although it does not mention any duel between Vali and Ravana.

While wandering in the Kronch forest with his brother Lakshmana in search of his wife Sita, who had been kidnapped by the rakshasa king Ravana, Rama encounters a gandharva stuck in the body of a distorted demon named Kabandha and kills him, freeing him from a curse. The freed Kabandha then advises Rama to seek Sugriva’s help in finding Sita.
