The Syngnathiformes / ˈsɪŋ (ɡ) nəθɪfɔːrmiːz / are an order of ray-finned fishes that includes the leafy seadragons, sea moths, trumpetfishes and seahorses, among others.

These fishes have elongated, narrow, bodies surrounded by a series of bony rings, and small, tubular mouths. The shape of their mouth—in at least syngnathids—allows for the ingestion of prey at close range via suction.

Syngnathids are found in temperate and tropical seas across the world. Most species inhabit shallow, coastal waters, but a few are known from the open ocean, especially in association with sargassum mats.

Syngnathiformes are found worldwide in tropical and temperate waters, with the greatest diversity in the Indo-Pacific. Although most species inhabit warm coastal marine waters, some live in freshwater and several tropical pipefishes are found in the lower reaches of rivers and streams.
