The Anglo-Russian invasion of Holland (or Anglo-Russian expedition to Holland, or Helder Expedition) was a military campaign from 27 August to 19 November 1799 during the War of the Second Coalition, in which an expeditionary force of British and Russian troops invaded the North Holland peninsula in the Batavian Republic. The campaign had two strategic objectives: to neutralize the Batavian fleet and to promote an uprising by followers of the former stadtholder William V against the Batavian government. The invasion was opposed by a slightly smaller joint Franco-Batavian army.

From a tactical standpoint, the Anglo-Russian forces were successful initially, defeating the defenders in the battles of Callantsoog, Krabbendam and Alkmaar, but subsequent battles went against the Anglo-Russian forces. Following a defeat at Castricum, the Duke of York, the British supreme commander, decided upon a strategic retreat to the original bridgehead in the extreme north of the peninsula. Subsequently, an agreement was negotiated with the supreme commander of the Franco-Batavian forces, General Guillaume Marie Anne Brune, that allowed the Anglo-Russian forces to evacuate this bridgehead unmolested. However, the expedition partly succeeded in its first objective, capturing a significant proportion of the Batavian fleet.
