Ivan Sratsimir, or Ivan Stratsimir, was emperor (tsar) of Bulgaria in Vidin from 1356 to 1396. He was born in 1324 or 1325, and he died in or after 1397. Despite being the eldest surviving son of Ivan Alexander, Ivan Sratsimir was disinherited in favour of his half-brother Ivan Shishman and proclaimed himself emperor in Vidin. When the Hungarians attacked and occupied his domains, he received assistance from his father and the invaders were driven away.

Vidin is a port city on the southern bank of the Danube in north-western Bulgaria. It is close to the borders with Romania and Serbia, and is also the administrative centre of Vidin Province, as well as of the Metropolitan of Vidin.
