It is the Slavic relative of the Latin name Johannes, corresponding to English John. This Slavic version of the name originates from New Testament Greek Ἰωάννης (Iōánnēs) rather than from the Latin Io(h)annes. The Greek name is in turn derived from Hebrew יוֹחָנָן (Yôḥānān, meaning “‘Yahweh is gracious’”). The name is ultimately derived from the Biblical Hebrew name יוחנן (pronounced [joχanan]), short for יהוחנן (pronounced [jəhoχanan]), meaning "Yahweh is merciful". Common surnames derived from the name Ivan, are Ivanović commonly used in Montenegro and Serbia. And Ivanov, commonly used in Russia and Bulgaria. "Ivanovich" is a Russian patronymic/middle name meaning "son of Ivan/John" or "Ivanson/Johnson".
Ivan is the most common male name in Bulgaria and Croatia. In Serbia, it was the 9th most common male name in the period of 1971–1980; 6th in 1981–1990; 9th in 1991–2000.
Since the 20th century, it has also been used as a popular given name among Italian (both the original form and the italianized version, Ivano), Spanish (as Iván), and Portuguese (sometimes Ivã) speaking peoples.
Its female form is Ivana. Ivanka is a variation on Ivana.
