Khǒr Royal Cup (Thai: ถ้วยพระราชทานประเภท ข.; ถ้วย ข.), known as the Noi Cup (Thai: ถ้วยน้อย) until 1963, was a part of the Thai football league system, founded by the Football Association of Thailand in 1916.
Khǒr Royal Cup was the second-highest level of the Thai football league system from 1916 to 1995. The Khǒr Royal Cup was downgraded to the third-tier tournament in 1996, replaced by the Thai Division 1 League. In 2006, the tournament was further downgraded to the fourth-tier of Thai football due to the proposed merger of the Provincial League and Thai Premier League into one entity. In 2016, the Khǒr Royal Cup was combined with Khor Royal Cup and Ngor Royal Cup into Regional League Division 3, and the tournament's cup become a trophy for Thai Division 1 League.
Each season or edition of the tournament was populated by clubs from its previous season which were neither promoted nor relegated, joined by the best four clubs promoted from the previous season of Khor Royal Cup. The first round was a group stage, with clubs divided into groups of 3 or 4 clubs. The winners and the runners-up of each group qualified to the knock-out stage. The finalists of the tournament were promoted to Regional League Division 2 for the following season, while the clubs which withdrew themselves from the tournament were relegated to Khor Royal Cup and Ngor Royal Cup for the following season.
