The 1986–87 Liga Bet season saw Hapoel Bnei Nazareth, Maccabi Isfiya, Maccabi Herzliya and Hapoel Ashdod win their regional divisions and promoted to Liga Alef. In the North A division, the final decisive match between Hapoel Bnei Nazareth and Maccabi Acre was postponed for over a month after league matches ended, and was eventually played on 13 June 1987. Nazareth won the match 2–0 and was promoted to Liga Alef.[1]
