Murphy is a city in suburban Collin County, Texas. The 2010 United States Census reported the population as 17,708. Murphy is located northeast of Dallas.

Murphy is a fast-growing community with a history that goes back to the early 1900s. Murphy is located in southern Collin county, within the Dallas/Fort Worth metroplex. Situated midway between Plano and Wylie on FM 544, Murphy is two miles (3 km) south of the famous Southfork Ranch. Its borders enclosing only 5.3 square miles (14 km²), Murphy shares borders with Plano, Richardson, Wylie, Sachse, and Parker. It is approximately 20 miles (32 km) from downtown Dallas and about 30 miles (48 km) from D/FW Airport.

The community supports plans to continue to foster the country-living atmosphere, though with fewer large lots. Minimum lot sizes are 9,000 square feet (840 m²), and the average lot size trends toward 12,000 square feet (1,100 m²).

Several subdivisions have begun building and are occupied. The newest approved development is 470 acres (1.9 km²) on the northeast side of the city along Maxwell Creek. The country living theme is expressed in this development by a linear park, which is expected to include a hike-and-bike trail. The major new feature to be noted in the Future Land Use Plan is a central business district at the northeast and northwest corners of the intersection of FM 544 and Murphy Road. This is expected to encompass a park-like area with offices and stores fronting on a central plaza. Construction on such a development, Murphy Marketplace, began in 2008. It now contains numerous restaurants and services. The municipal complex comprises a total of five buildings to serve Fire, Police, City Administration, and Public Works, as well as a 2014 addition of the PSA Murphy sports center.
