The Aindra (of Indra) school of Sanskrit grammar is one of the eleven schools of Sanskrit grammar mentioned in Pāṇini's Ashtadhyayi. It is named after Indra in allusion to Lord Indra, the king of Gods in Hindu mythology. Arthur Coke Burnell, a renowned orientologist, in his 1875 book, "On the Aindra school of Sanskrit grammars" details this school. Burnell believed that most non-Pāṇinian systems of Sanskrit grammar were traceable to this school of grammar, believed to be the oldest and reputed to be founded by Indra himself.
