Church of Saint Stephen was a 10th-century church in Salona, currently an archaeological site located in today's Solin, Croatia. Its atrium served as a mausoleum of Croatian medieval rulers. It is one of the two medieval churches on the site, the other being dedicated to the Virgin Mary.

According to writings of 13th century medieval chronicler, Thomas the Archdeacon, the Church of St. Stephen was built by queen Helen of Zadar, who then donated them to diocese of Split. Thomas claims, that the churches were temporarily given to some monks who performed rituals there, due to the royal tombs being inside, until king Zvonimir of Croatia donated them back to the diocese of Split.^[1] Thomas noted on:

"that's where magnificent man king Krešimir rests, along with many other kings and queens in atrium of basilica of St. Stephen".^[1]

Although this area was affected by the Mongol invasions of 13th century, who chased Hungarian king Bela IV all the way to Dalmatia and besieged the nearby Klis fortress, most Croatian scholars nowadays agree that the church of St. Stephen survived these invasions, since it is still visible on 14th century maps. They presume, however, that it was destroyed somewhere in early 16th century, during the Ottoman invasions.^[2][3]

In this tomb rests queen Helen, servant of God, wife of king Michael, mother of king Stephen [...] On the eight day, month of October, she was buried here, 976th year after ascention of Lord [...] She, who was during her life a mother of Kingdom, became (the mother) of poor and protector of widows. By looking here, say thou man: God, give mercy to her soul!"[5]
