Jonathan (Hebrew: יְהוֹנָתָן/יוֹנָתָן‎, Standard: Yəhōnatan/Yōnatan, Tiberian: Yо̆hōnāṯān/Yōnāṯān) is a common name given to males which means "YHWH has given" in Hebrew. The earliest known use of the name was in the Bible; one Jonathan was the son of King Saul, a close friend of David.

Variants of Jonathan include Jonatan, Djonathan. Biblical variants include Yehonathan, Y'honathan, Yhonathan, Yonathan, Yehonatan, Yonatan, Yonaton, Yonoson, Yeonoson or Yehonasan. In Israel, "Yoni" is a common nickname for Yonatan (Jonathan) in the same way Jonny is in English. In Latin America both "Jhonny" and "Johnny" coexist due to misspelling and have become commonly used (Jhonny Peralta, Jhonny Rivera, Jhonny da Silva).

The name was the 31st-most-popular boys' name in the United States in 2011, according to the SSA.
