The Murphy-Hill Historic District encompasses the oldest residential portion of the city of El Dorado, Arkansas. It is located just north of the central business district, bounded on the north by East 5th Street, on the west by North Jefferson and North Jackson Avenues, on the east by North Madison Avenue, and on the south by East Peach and East Oak Streets. Six of the 76 houses in the 40-acre (16 ha) district were built before 1900, including the John Newton House, one of the first buildings to be built in El Dorado. Of particular note from this early period is a highly elaborate Queen Anne Victorian at 326 Church Street.
