Aschaffenburg (Low Franconian: Aschebersch) is a Landkreis (district) in Bavaria, Germany. It is bounded by (from the west and clockwise) the districts of Darmstadt-Dieburg, Offenbach, Main-Kinzig (all in the state of Hesse), the districts Main-Spessart and Miltenberg, and the City of Aschaffenburg.

The Aschaffenburg history goes back as far as the year 957. Initially, being a Roman settlement, it came under the authority of the electors of Mainz in 982 and was chartered in 1173. Remains of Roman settlements were found on the river Main. There was a Roman military camp in today's municipality of Stockstadt am Main. After the Roman retreat, the region became subject to Alemanni and Franks before becoming a part of the Electorate of Mainz. While the banks of the Main were populated all these centuries, the hills of the Spessart were virtually unsettled until the 13th century.

The districts of Aschaffenburg and Alzenau were established in 1862, half a century after the state of Bavaria annexed the region. These districts were merged in 1972 to form the present district.

The district is located in the extreme northwest of Bavaria and bounded by Hesse on two sides. The Main river forms the western border, though southwest of the town of Aschaffenburg, parts on the western river banks are incorporated into the district. The south and east of the district extends into the Mittelgebirge Spessart.

The town of Aschaffenburg is not included in the district ( kreisfrei ), but is nonetheless its administrative seat.

The geographic centre of the European Union was located in the District of Aschaffenburg from 2013 to 2020.

In 2017 (latest data available), the GDP per inhabitant was €33,109. This places the district 60th out of 96 districts (rural and urban) in Bavaria (overall average: €46,698).
