The 1940 Liga Bet season was the second-tier league of the Palestine League organized by the EIFA. The league was split into three regional divisions: North, Samaria and South. The Samaria division was won by Degel Zion Tel Aviv, while Hapoel Hadera won the North division and a British military team, RSG, which competed in the league as a guest, won the South Division.

At the end of the season, Degel Zion, Hapoel Hadera and Hapoel Rishon LeZion (who finished as runners-up in the South division) competed for promotions to the top division. Hapoel Rishon leZion and Degel Zion won the two top places and were promoted.
