The Battle of Vaslui (also referred to as the Battle of Podul Înalt or the Battle of Racova) is fought on January 10, 1475, between Stephen III of Moldavia and the Ottoman governor of Rumelia, Hadım Suleiman Pasha.

The battle takes place at Podul Înalt (the High Bridge), near the town of Vaslui, in Moldavia (now part of eastern Romania).

The Ottoman troops number up to one hundred and twenty thousand, facing about forty thousand Moldavian troops, plus smaller numbers of allied and mercenary troops.

Stephen inflicts a decisive defeat on the Ottomans, with casualties, according to Venetian and Polish records, reaching beyond forty thousand on the Ottoman side.

Mara Brankovic (Mara Hatun), the former younger wife of Murad II, tells a Venetian envoy that the invasion had been the worst ever defeat for the Ottomans.

[ Stephen is later awarded the title "Athleta Christi" (Champion of Christ) by Pope Sixtus IV, who refers to him as "verus christianae fidei athleta" ("the true defender of the Christian faith").

According to the Polish chronicler Jan Długosz, Stephen did not celebrate his victory; instead, he fasted for forty days on bread and water and forbade anyone to attribute the victory to him, insisting that credit be given only to "The Lord".
