The first Philadelphia Koreatown (Hangul: ) was located in the Olney section of the city of Philadelphia, United States. Since the late 1980s, the Korean community has expanded northward, and it now straddles the border between Philadelphia proper and the suburb of Cheltenham, although many Korean-American businesses and organizations and some residents remain in Olney and adjoining neighborhoods. Upper Darby Township, bordering West Philadelphia, also has a large Korean-American population; meanwhile, a rapidly growing Korean population and commercial presence has emerged in nearby suburban Cherry Hill, New Jersey since 2010, centered along Marlton Pike.
According to the Philadelphia Inquirer, the Koreatown had "moved" from the Logan neighborhood into the Olney section in the early 1980s, attributing the migration from Logan to "too much crime" and the "schools weren't so good" at the time in Logan. In Olney, tensions were high between Koreans and the German community, as well as the black community, who did not want the section of the town to be officially declared "Koreatown", causing much violence and crime to be committed not only against Koreans, but Asians in general. The original Koreatown existed on North 5th Street in Olney since 1984, with Korean language signs put up to help official recognition of the area; those signs were vandalized in the late 1980s. Today, that section of town has transitioned into the Puerto Rican neighborhood call El Centro de Oro.
