The Emperor's Cup JFA All-Japan Football Championship Tournament (Japanese: 天皇杯 JFA 全日本サッカー選手権大会, Hepburn: Tennōhai Jēefuē Zen-Nihon Sakkā Senshuken Taikai), commonly known as The Emperor's Cup (Japanese: 天皇杯, サッカー天皇杯, Hepburn: Tennōhai, Sakkā Tennōhai) or Japan FA Cup, and rebranded as The JFA Emperor's Cup from 2024 onwards, is a Japanese annual football competition. It has the longest tradition of any football tournament in Japan, dating back to 1921, before the formation of the J.League, the current JFL (not the former JFL), and their predecessor, the Japan Soccer League.

Before World War II, teams could qualify not only from Japan proper but also from Empire of Japan's colonies such as Korea, Taiwan, and sometimes Manchukuo. The winning club qualifies for the AFC Champions League and the Japanese Super Cup. The tournament's equivalent in women's football is the Empress's Cup.

The current holders are Machida Zelvia, having won their first cup in the 2025 edition.
