Pratijnayaugandharayana (Sanskrit: प्रतिज्ञायौगन्धरायणम्, Pratijñāyaugandharāyaṇam) (English: The Pledge of Minister Yaugandharāyaṇa) is a Sanskrit play in four acts written by the ancient Indian poet Bhāsa. It is the oldest extant political play of India[1] and the prequel to Bhāsa's Svapnavasavadattam.[2][3][4] These plays were written by Bhāsa on the account of Udayana, king of Vatsa (Kaushambi).
Throughout the play, Yaugandharayana, minister of Udayana, takes two vows which are ultimately fulfilled.[5]
