Břeclav District borders Austria in the south and Slovakia in the southeast. The territory of the district is predominantly lowland and belongs to the warmest areas in the country. The territory extends into five geomorphological mesoregions: Lower Morava Valley (most of the territory), Mikulov Highlands (southwest), Dyje–Svratka Valley (west), Ždánice Forest (north) and Kyjov Hills (small part in the northeast). The highest point of the district is the mountain Děvín in Pavlov with an elevation of 550 m (1,800 ft). The lowest point of the district and entire South Moravian Region is the confluence of the Morava and Thaya rivers in Lanžhot at 150 m (490 ft).

From the total district area of 1,038.0 km (400.8 sq mi), agricultural land occupies 682.0 km (263.3 sq mi), forests occupy 177.9 km (68.7 sq mi), and water area occupies 54.5 km (21.0 sq mi). Forests cover 17.1% of the district's area.

The longest river in the area is the Morava, which forms the Czech-Slovak border. However, the most important river for the district is the Thaya, which flows across the territory from northwest to south and briefly forms the Czech-Austrian border before the confluence with the Morava. The Kyjovka flows to the Thaya through the southeastern part of the district. The Svratka crosses the district in the northwest, otherwise there are no major rivers in the northern part of the district.

Most of the Nové Mlýny reservoirs lie in the district and are the largest body of water of the district. On the Včelínek River is a system of several large ponds, including Nesyt, which belongs to the largest ponds in the country.

Pálava Protected Landscape Area is a protected area that lies entirely in the district.
