Peachtree Corners is a city in western Gwinnett County, Georgia, located along the Chattahoochee River in the northeastern suburbs of Atlanta. It is the largest city in Gwinnett County, with a population of 42,243 at the 2020 census. The city's name and character are tied to the river, and the Chattahoochee remains central to recreation and daily life throughout the community. The area's modern identity began with Technology Park, a business campus established to attract high-tech employers and, later, STEM-focused education. That legacy endures and distinguishes Peachtree Corners from many of its suburban neighbors. The city was officially incorporated in 2012, consolidating a collection of long-established neighborhoods and commercial corridors into a single municipality, which now ranks as Gwinnett's most populous city. Peachtree Corners is also known for its deliberate investment in a walkable center. The 21-acre Town Center, built around a two-acre Town Green, brings together restaurants, retail, offices, co-working space, and townhomes in a compact, pedestrian-friendly district that hosts concerts and community events throughout the year. This mix of established neighborhoods, corporate campuses, and a lively center gives the city a blend of suburban comfort and urban amenity. The city's riverfront setting supports kayaking, fly fishing, and tubing, while its schools — including a dedicated STEM high school within Technology Park — are a significant draw for families. Neighborhoods range from established golf and swim-tennis communities to newer mixed-use residences, giving buyers a broad spectrum of housing types within a single well-regarded school district. For homebuyers, Peachtree Corners offers strong public schools, riverfront recreation, and highway access into the broader Atlanta region, all within one of Gwinnett County's most recognizable addresses.
