Los láridos (Laridae) son una familia de aves del orden Charadriiformes conocidas vulgarmente como gaviotas. Están estrechamente relacionadas con los charranes de la familia Sternidae, y más lejanamente con las aves zancudas. La mayoría de las gaviotas pertenece al género Larus.
Son en general aves grandes, en su mayoría de plumaje gris, blanco o negro, a menudo con señales negras en la cabeza o las alas. Tienen picos robustos, bastante largos.
Las gaviotas son especies típicamente costeras marinas o costeras de lagos y lagunas interiores, y vuelan grandes distancias. Las especies de mayor tamaño tardan hasta cuatro años en lograr el plumaje adulto pleno, si bien a los dos años la mayoría de las especies de gaviotas pequeñas tienen plumaje adulto.

Gulls (often informally called seagulls) are birds in the family Laridae. They are most closely related to the terns (family Sternidae) and only distantly related to auks, skimmers, and more distantly to the waders. Until recently, most gulls were placed in the genus Larus, but this arrangement is now known to be polyphyletic, leading to the resurrection of several genera.
They are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls. They have stout, longish bills, and webbed feet. Gull species range in size from the Little Gull, at 120 g (4.2 oz) and 29 cm (11.5 inches), to the Great Black-backed Gull, at 1.75 kg (3.8 lbs) and 76 cm (30 inches).
Most gulls, particularly Larus species, are ground nesting carnivores, which will take live food or scavenge opportunistically. Live food often includes crabs and small fish. Apart from the kittiwakes, gulls are typically coastal or inland species, rarely venturing far out to sea. The large species take up to four years to attain full adult plumage, but two years is typical for small gulls. Large White-Headed Gulls are typically long-lived birds, with a maximum age of 49 years recorded for the Herring Gull.
