Sachse (/ˈsæksi/ SAK-see) is a city in Collin and Dallas counties in the U.S. state of Texas and is part of the DFW metroplex. A northeastern suburb of Dallas, the city population was 27,103, as of the 2020 census with an estimated population of 33,768 people today. Sachse is located off Texas State Highway 78 and President George Bush Turnpike (Texas State Highway 190) and is approximately 1 mile (1.6 km) north of the Firewheel Town Center.

Sachse was founded by William Sachse, a European immigrant from Herford, Prussia (modern-day North Rhine-Westphalia), in 1845. Purchasing 640 acres (2.6 km) from Collin County, Sachse erected the first cotton mills and gins in the county. After Sachse gave 100 feet of frontage through all of his holdings to the railroad in 1886, the railroad built a depot on the frontage and named the town Sachse. Since the depot was labeled 'Saxie', many old legal documents referred to the city as 'Saxie'. The flaw was later corrected. The word Sachse comes from the German word for Saxon.

According to the United States Census Bureau, the city has a total area of 25.6 square kilometers (9.9 sq mi), of which 25.2 km (9.7 sq mi) is land and 0.4 km (0.2 sq mi) (1.62%) is water.
