I Liga Women (Poland) 2026/27

The I Liga Kobiet operates as the third tier of the national women's handball pyramid in Poland. Situated below the ORLEN Superliga Kobiet and the Liga Centralna Kobiet, the competition underwent a structural shift in the 2023/2024 season when the introduction of the second-tier league demoted this division from its historical status as the second level. Organized by the Polish Handball Federation (Związek Piłki Ręcznej w Polsce - ZPRP), the league functions as a developmental pathway for promotion rather than a centralized professional entity.

The 2024/2025 season features 31 teams divided into three geographical groups, designated A, B, and C. Each group operates on a round-robin format. Progression to the second tier is determined through the Turniej Mistrzyń (Mistresses' Tournament), a final tournament contested by the winners of the three I Liga groups. Relegation details to the fourth-tier II Liga are not explicitly defined in current public summaries.

Unlike the upper tiers, this competition is semi-professional and geographically segmented. While the top-tier league dates back to 1939, and references to "1 Liga" appear as early as the 1961/62 season, the specific founding year of the I Liga as a distinct second-tier entity is not clearly established due to historical restructuring. No single club holds a definitive record for the most titles in the I Liga due to the league's group-based structure and historical renumbering from II Liga to I Liga. Notable clubs frequently competing in this tier include KS Piła, AZS AWF Poznań, and Otmęt Krapkowice.
