Kohen (or Kohain; Hebrew: כֹּהֵן‎‎, "priest", pl. כֹּהֲנִים Kohanim) is the Hebrew word for priest. Jewish Kohanim are traditionally believed and halachically required to be of direct patrilineal descent from the Biblical Aaron.

The noun kohen is used in the Torah to refer to priests, both Jewish and non-Jewish, such as the Jewish nation as a whole, as well as the priests (Hebrew kohanim) of Baal (2Kings 10:19). During the existence of the Temple in Jerusalem, Kohanim performed the daily and holiday (Yom Tov) duties of sacrificial offerings.

Today kohanim retain a lesser though somewhat distinct status within Judaism, and are bound by additional restrictions according to Orthodox Judaism.

The Hebrew noun kohen is most often translated as "priest", whether Jewish or pagan, such as the priests of Baal or Dagon, though Christian priests are referred to in Hebrew by the term komer (Hebrew כומר). The word derives from a Semitic root common, at minimum, to the Central Semitic languages; the cognate Arabic word كاهن kāhin means "soothsayer, augur, or priest".

Leonard Norman Cohen, CC GOQ (born 21 September 1934) is a Canadian singer-songwriter, musician, poet, and novelist. His work often explores religion, isolation, sexuality, and interpersonal relationships. Cohen has been inducted into the American Rock and Roll Hall of Fame and both the Canadian Music Hall of Fame and the Canadian Songwriters Hall of Fame. He is also a Companion of the Order of Canada, the nation's highest civilian honour.

While giving the speech at Cohen's induction into the Rock and Roll Hall of Fame on 10 March 2008, Lou Reed described Cohen as belonging to the "highest and most influential echelon of songwriters."

Cohen was born on 21 September 1934 in Westmount, Montreal, Quebec, into a middle-class Jewish family. He attended Roslyn Elementary School. His mother, Marsha Klinitsky, of Lithuanian Jewish ancestry, emigrated from Lithuania while his great-grandfather emigrated from Poland. He grew up in Westmount on the Island of Montreal. His grandfather was Lyon Cohen, founding president of the Canadian Jewish Congress. His father, Nathan Cohen, who owned a substantial Montreal clothing store, died when Cohen was nine years old. On the topic of being a Kohen, Cohen has said that, "I had a very Messianic childhood." He told Richard Goldstein in 1967. "I was told I was a descendant of Aaron, the high priest." Cohen attended Westmount High School, beginning in 1948 where he was involved with the Student Council and studied music and poetry. He became especially interested in the poetry of Federico Garcia Lorca. As a teenager, he learned to play the guitar, and formed a country-folk group called the Buckskin Boys. Although he initially played a regular acoustic guitar as a teenager, he soon switched to playing a classical guitar after meeting a young Spanish flamenco guitar player who taught him "a few chords and some flamenco."
