An iridium‐catalyzed selective ortho‐monoiodination of benzoicacids with two equivalent C−H bonds is presented. A wide range of electron‐rich and electron‐poor substrates undergo the reaction under mild conditions, with >20:1 mono/di selectivity. Importantly, the C−H iodination occurs selectively ortho to the carboxylic acid moiety in substrates bearing competing coordinating directing groups. The
