Roberto Ubaldini (1581 – April 22, 1635) was a bishop and cardinal of the Catholic Church.
He was born in Florence. He was appointed Bishop of Montepulciano in 1607, and ordained to that post in 1608. He was elevated to the status of cardinal in 1615, and made Prefect of the Sacred Congregation of the Council in 1621. He resigned from that position in 1623, shortly after resigning his position as bishop.
