Ioan I Joldea (pronunciation: [jo̯an-ʒolde̯a]) was Prince of Moldavia for a few days in September 1552.^[1]

Ioan Joldea, a Moldavian boyar with the commission rank, was chosen lord in Țuţora by the Sturza and Moghila boyars, after the murder of Ștefan VI Rareș on September 8, 1552. This fact sparked hostilities in Krakow. King Sigismund II Augustus was going to enthrone Alexandru Lăpușneanu, the son of Bogdan III the One-Eyed, in Suceava. Joldea had chosen Ruxandra, the daughter of Petru Rareș, as his wife, in order to be entitled to occupy the throne of the country.

Joldea was heading to Suceava to be anointed lord, but his mistake was the stop at Șipote. Alexandru Lăpușneanu, with support from the nobles Mikołaj Sieniawski and Moțoc, tricked Joldea and his loyal boyars. Joldea was mutilated and removed by Alexander Lăpușneanu.
