Ivan (Cyrillic: Иван / Іван) is a male given name of Slavic origin, related to a variant of the Greek name Iōánnēs (English: John), which in turn derives from the Hebrew יוֹחָנָן (Yôḥānnān), meaning "God is gracious." The name is strongly associated with Slavic countries and cultures. The earliest known bearer was the Bulgarian Saint Ivan of Rila. Ivan is a very common name in Russia, Ukraine, Croatia, Serbia, Bosnia and Herzegovina, Slovenia, Bulgaria, Belarus, North Macedonia, and Montenegro. It has also gained popularity in several Romance-speaking countries since the 20th century.
