Sukho (Russian: Сухо) is a small artificial island located in the south-east of Lake Ladoga 20 km near its southern shore.

According to legend, Peter I discovered the shoal by grounding on it while sailing from Volkhov Bay in a yal, exclaiming: "it's dry here!"

He ordered all passing vessels to leave stones on the shoal to build the island, which became known as Sukho (Dry).

During the Second World War, the Soviets garrisoned Sukho to help secure the southern part of the lake.

An Axis amphibious assault on the island in October 1942 using armed Siebel ferries suffered heavy losses to neutralize the Soviet shore battery; it marked the end of effective Axis offensive activity on the lake.
