The River Tern (also historically known as the Tearne) is a river in Shropshire, England. It rises north-east of Market Drayton in the north of the county. The source of the Tern is considered to be the lake in the grounds of Maer Hall, Staffordshire. From here it flows for about 30 miles (48 km), being fed by the River Meese and the River Roden, until it joins the River Severn near Attingham Park, Atcham.
Extensive peat bog formerly existed, extending from Crudgington on the Tern as far as Newport.


At Longdon-on-Tern, the Tern is spanned by the Longdon-on-Tern Aqueduct, the world's first large-scale cast iron navigable aqueduct (Benjamin Outram's 13 m cast iron Holmes Aqueduct pre-dated it by a month), designed by Thomas Telford to carry the Shrewsbury Canal. Although no longer connected to the canal network, The 62-yard (57 m) long structure still stands, but is marooned in the middle of a field.

The Indian river tern or just river tern (Sterna aurantia) is a tern in the family Laridae. It is a resident breeder along inland rivers from Iran east into the Indian Subcontinent and further to Myanmar to Thailand, where it is uncommon. Unlike most Sterna terns, it is almost exclusively found on freshwater, rarely venturing even to tidal creeks.
This species breeds from March to May in colonies in less accessible areas such as sandbanks in rivers. It nests in a ground scrape, often on bare rock or sand, and lays three greenish-grey to buff eggs, which are blotched and streaked with brown.
This is a medium-sized tern, 38–43 cm long with dark grey upperparts, white underparts, a forked tail with long flexible streamers, and long pointed wings. The bill is yellow and the legs red. It has a black cap in breeding plumage. In the winter the cap is greyish white, flecked and streaked with black, there is a dark mask through the eye, and the tip of the bill becomes dusky. The sexes are similar but juveniles have a brown head, brown-marked grey upperparts, grey breast sides and white underparts. The bill is yellowish with a dark tip


As with other Sterna terns, the river tern feeds by plunge-diving for fish, crustaceans, tadpoles and aquatic insects in rivers, lakes, and tanks. Its numbers are decreasing due to the pollution of their habitat.
