Gifhorn (German pronunciation: [ˈɡɪfhɔʁn]) is a district in Lower Saxony, Germany.

The southern terminus of the Elbe Lateral Canal at the Mittellandkanal is at Edesbüttel in the district.

The lowest point of the administrative district Gifhorn lies at the Aller near Müden (46 m (151 ft) above sea level).

The highest point lies in the north of the district near Sprakensehl (124 m (407 ft) above sea level).

In 1974 the district again lost parts of its territory, when the city of Fallersleben was incorporated into Wolfsburg.
