Police Chief of Mouseton with a stereotypical Irish background. His first appearance was in the Phantom Blot tale when O'Hara's chief Detective, Mr. Casey was assigned to solve the case, but it took the cunning of Mickey Mouse instead. Chief O'Hara has been a constant figure playing a prominent role in many other Mickey Mouse mysteries.
O'Hara also appeared on Mickey Mouse Works and Disney's House of Mouse.
The character was conceived by Floyd Gottfredson (and Merrill De Maris) for Disney as a stereotypical Irish cop. He first appeared in the newspaper strips in May 1939, in the serial "Mickey Mouse Outwits the Phantom Blot". In the German translations of the comics, he is known as "Kommissar Albert Hunter" (Kommissar means commissioner in German), in the Swedish versions as "Kommissarie Karlsson", in the Danish versions as "Politimester Striks", in the Italian version as "Commissario Adamo Basettoni", and in the Brazilian version as "Coronel Cintra". In the Finnish translation he is known as "Poliisimestari Sisu", possibly named after the Finnish concept of sisu. In Italian stories O'Hara has a wife called Petulia.
