The Longfin Inshore Squid (Loligo pealei) is a species of squid of the family Loliginidae. The species is sometimes referred to by only its genus name Loligo. The Longfin Inshore Squid is found in the North Atlantic, schooling in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela. It is commercially exploited, especially in the range from Southern Georges Bank to Cape Hatteras.

The Longfin Inshore Squid spawns year-round and lives for less than one year. Individuals hatched in summer generally grow more rapidly than those hatched in winter. The species presents sexual dimorphism, with most males growing faster and reaching larger sizes than females. The dorsal-mantle length of some males can reach 40 cm, although most squids commercially harvested are smaller than 30 cm long.

This species is a model organism in neuroscience and was used by Andrew Huxley and Alan Hodgkin in their studies on axons.
