Lalling is a municipality in the Lower Bavarian district of Deggendorf in Germany.

Lalling is located along the Danube in the south of the Bavarian Forest, specifically in what is called the Lallinger angle.

Lalling and its community were first mentioned in a letter of protection from Pope Eugene III in 1148.

From the early 13th Century until 1803 the Niederaltaich Abbey was its largest landlord.

Lalling was considered part of the lands held by the Electorate of Bavaria.
