Dacula (/dəˈkjuːlə/ də-KEW-lə) is a city in Gwinnett County, Georgia, United States, located approximately 37 miles (60 km) northeast of Atlanta.

The Dacula area is home to some of the oldest buildings in northeast Georgia, such as the Elisha Winn House, which originally acted as the courthouse for Gwinnett County.

After settlers lobbied for the ethnic cleansing of the Nation, the Trail of Tears (through the Indian Removal Act) made it easier for Dacula and the unannexed portions of Gwinnett to be settled.

[13] Since the project's approval, the Dacula area has seen an increase in both suburban residential and strip mall commercial changes, including the Harbins 316 development, which massively expanded food and amenity access to a portion of Gwinnett County that previously had to drive 30–40 minutes to a grocery store.

The town unveiled a new playground and workout area in Maple Creek Park in 2024, and continues its renowned Memorial Day Parade.

[5] The Dacula 30019 ZIP code goes well beyond the city limits, resulting in mail delivery as far north as the unincorporated community of Hamilton Mill, south of Interstate 85.

[21] The town of Dacula is served by two newspapers: the Gwinnett Daily Post (based in nearby Lawrenceville) and the Hamilton Mill Neighborhood News.
