Jonas Vaidutis (Latin: Waydutte; Polish: Jan Wajduta Butawtowicz; 1365 – spring 1402) was a Lithuanian duke, priest, and academic rector from the Gediminid dynasty. Vaidutis was a son of duke Butautas and a grandson of the former Lithuanian monarch Kęstutis. He titled himself as the Duke of Drohiczyn.

He held the positions of the Custos of the Franciscans of Kraków and the Canon of Kraków and Sandomierz. From 1401 to 1402, the year of his death, he was the Rector of the Jagiellonian University in Kraków.

According to Czech philologist Tomáš Hoskovec, Vaidutis was the first ethnic Lithuanian to be a European intellectual. Lithuanian-American historian Vanda Sruogienė deemed him the earliest known Lithuanian to graduate from a university. His pre-Christian Lithuanian name Vaidutis is sometimes confused with that of his uncle Vaidotas.
