Aviv (Hebrew: אביב) means "spring (season)" in Hebrew. Aviv is the first month of the year in the Pentateuch, and is later called Nisan in the book of Esther and in subsequent post-exilic history up to the present day. These names are sometimes used interchangeably, although Aviv refers to the three-month season, and Nisan is called the "first month of Aviv." Aviv is also used as a given name, surname, and place name, as in Tel Aviv.

Aviv is a Hebrew male and female name. The feminine version of the name is Aviva. Aviv is also an old and uncommon Russian Christian male given name "Ави́в" (Aviv), that possibly borrowed from Biblical Hebrew, where it derived from the word abīb, meaning an ear or a time of year where grains come into ear, also known as "Aviv" (or Nisan—the first month of the Hebrew calendar). The diminutives of "Aviv" in Russian are Aviva (Ави́ва) and Viva (Ви́ва). The patronymics derived from "Aviv" are "Ави́вович" (Avivovich; masculine) and "Ави́вовна" (Avivovna; feminine).
