Elon (אֵילוֹן (Hebrew)), Alon (אַלוֹן (Hebrew)) or Ilan (אִילָן (Hebrew)) is a Jewish masculine name of Hebrew origin. The name means "tree" or "oak tree" in the Hebrew language. Elon is a rare male first name as it was not ranked for males of all ages in the United States Census, 1990. It is also used in many countries in a feminine sense, as the girl's name "Ilana". Moreover, the Jewish holiday of Tu B'Shvat, the "new year of the trees" is referred to in Hebrew as "Rosh HaShanah La'Ilanot", where "Ilanot" is the feminine plural Hebrew word for tree.
