Nida is a resort town in Lithuania, the administrative centre of Neringa municipality. Located on the Curonian Spit between the Curonian Lagoon and the Baltic Sea, it is the westernmost point of Lithuania and the Baltic states, close to the border with the Russian Kaliningrad Oblast exclave. It currently has about 2,385 residents.

The town is an upmarket holiday resort, hosting about 200,000 to 300,000 tourists each summer, mostly Lithuanians, Germans, Latvians, and Russians. It is characterized by low-key entertainment and a distinct family focus. However, during recent years it has become a decent point of interest for fine electronica music and modern art shows at an eclectic forest retreat.

Since 2001, a jazz festival has been held every year. A local radio station Neringa FM streams live beats over FM and online. There are also interesting places to see nearby, including some of the highest sand dunes in Europe, a large sundial (which has been restored after being damaged by a Baltic gale), Fisherman's Ethnographic Homestead, gallery-museum of amber and a German Protestant (Evangelische) Brick Gothic church (built in 1888). There is also a campsite.

The town is known for Nidden Kurenwimpel - German for "Curonian pennants" - ornate carved flags particular to local families resident on the Curonian Spit. The flags, replicas of which can be seen around Nida, feature animal and human figures as pictograms reminiscent of a pagan writing tradition. At the local cemetery, examples of krikštas (pl. krikštai), pagan burial markers in place of tombstones, can still be seen.

Nida's beach participates in the Blue Flag Programme. Nudists make use of parts of the beach near Nida for nude bathing.
