The New England Flood of May 2006, often locally referred to as the Mother's Day Flood, was a flood event that occurred in New England, especially in New Hampshire and Massachusetts, during the month of May, 2006. It started on May 11, 2006 as a result of an unusually strong low pressure system that stalled over the central United States, drawing copious amounts of moisture from the Atlantic Ocean. Most of this moisture was drawn directly over New England, producing continuous heavy rain that led to record flooding near several rivers. It was described as the worst flooding since the New England Hurricane of 1938. There were at least two fatalities, both in Topsfield, Massachusetts. Some called it the Mother's Day Flood, since it occurred on that holiday.

The geology of New Hampshire is similar to that of the rest of New England in comprising a series of metamorphosed sedimentary and volcanic rocks of Late Proterozoic to Devonian age, intruded by many plutons and dikes ranging in age from Late Proterozoic to early Cretaceous. New Hampshire is known as "the Granite State", but less than half is underlain by granite; much of it is schist or gneiss, both of which are metamorphic rocks.
