The long-jawed orb weavers or long jawed spiders (family Tetragnathidae) are elongated spiders with long legs and chelicerae.

The spiders are orb web weavers, weaving small orb webs with an open hub and few, wide-set radii and spirals. The webs have no signal line and no retreat. Some species are often found in long vegetation near water.

The genus Nephila, or golden silk orb-weavers, named after the golden tint of their silk, has been separated into its own family, Nephilidae.
