The Egyptian Second Division B (Arabic: دوري القسم الثاني المصري "ب") is the third tier of the Egyptian football league system starting from the 2023–24 season. It replaces the Egyptian Third Division on the pyramid. It is administered by the Egyptian Football Association. It is below the second professional league in the country, the Egyptian Second Division A, and above the Egyptian Third Division.
In 2022, after Gamal Allam was elected for the presidency of the EFA, the idea to restructure the old Egyptian Second Division emerged again, and a series of major changes were announced. This was confirmed later the same year, and it was announced that the second division will be abolished, and two new leagues, known as Second Division A and Second Division B, will be created as the new second and third tier leagues, respectively, with the latter retaining a format similar to the one used by the old second division.
The reformation decision meant that the 2022–23 Egyptian Second Division season will be the last edition of the competition, which will see 28 out of the 48 participating teams earning a spot in the inaugural season of the Egyptian Second Division B.
