International Arbiter is a title awarded by FIDE to individuals deemed capable of acting as arbiter in important chess matches. The title was established in 1951.

Requirements for the title to be awarded are detailed in section B.06 of the FIDE Handbook. As well as thorough knowledge of the laws of chess and a proved impartiality, they include the ability to speak a FIDE-approved language and previous experience as an arbiter in important tournaments. International Arbiters are further categorized by FIDE into four groups, in order of experience, from group D, C, B to A. The FIDE World Chess Federation displays the list of International Arbiters with their ID numbers, name, and title on its official website.
