Ins (German: [ɪns]; French: Anet [anɛt]) is a municipality in the Seeland administrative district in the canton of Bern in Switzerland.

Ins is first mentioned in 1009 as Anestre. In 1179 it was mentioned as Anes.

The area around Ins has been inhabited since at least the Iron Age. On Schaltenrain hill, individual graves and groups of grave mounds have been found stretching over 2 km (1.2 mi) of the hill. At least four different sites have been discovered. The first excavation was carried out under the direction of Gustav von Bonstetten in 1848, who placed his discoveries in the Historical Museum of Berne. In the following year, Emanuel F. Müller excavated other sites on the hill. The third large excavation was in 1908-09 under Jakob Heierli, who placed his finds in the Museum Schwab in Bienne. Due to the number and variety of artifacts, smaller sites and individual items continue to be discovered.

Bonstetten's excavations discovered a minimum of ten grave mounds, 1.8–4.5 m (5.9–14.8 ft) in height, arraigned in a line. The sixth mound contained two Hallstatt "wagon graves" (graves containing wagons or parts of a wagon) from the 7th century BC. Golden objects found in this mound and other nearby mounds show an Etruscan influence or were produced on the Italian peninsula and traded. In addition to gold and the wagons, jewelry made from glass, amber, lignite, pearls and bronze were found. An early La Tène iron sword from the 5th century BC was also found. The richness of the finds and the relatively long settlement duration indicates that this was a wealthy and successful settlement that traded with the Mediterranean.

During the Roman era there was a wide band of settlements that stretched from the Grosses Moos marsh up into the vineyard covered hills. A Roman road ran through the march and connected the settlements with the Roman towns of the Swiss Plateau.

During the Middle Ages Fenis Castle, the seat of the Counts of Fenis, was built on the Hasenburg which is now part of the municipality of Ins. During the Late Middle Ages the village was part of the Herrschaft of Erlach. During the Burgundian Wars, the village along with the Herrschaft of Erlach was annexed by Bern. Under the new Bernese Bailiwick of Erlach, Ins remained an important regional administration center.

The former village church of St. Mary was first mentioned as a romanesque building in 1228. However, since it was located close to an early medieval cemetery, it was probably built over or near an earlier church. It was rebuilt in the 16th and 17th centuries. The church's patronage rights were held by the Cathedral of Bern until the Protestant Reformation ended it in the 16th century.

Historically the village was surrounded by extensive vineyards. The nearby Grosses Moos marsh was a source of peat from the 18th until the early 20th century. The village was a regional administration and financial center. The old Rathaus was used as the seat of the low court until it burned down in 1848. The village Landgerichtsplatz held the stone Landstuhl for the Landvogt and benches for his court. A tithe barn was built in 1680 for the parish. During the 17th and 18th century wealthy landowners built elegant manor houses in the village, including the Schlössli, Lilienhof, Altes Spital and Wagnerhaus.

Ins is located on the southern slope of the Schaltenrain (592 m (1,942 ft)) and stretches over part of the Grand Marais, a particularly productive area with nearly black soil in the Bernese Seeland. On the south it is bordered by Lake Neuchatel and the Broye Canal. It includes the settlement of Witzwil im Moos and several scattered, individual farm houses.

Despite being a small municipality, Ins serves as a center for the neighbouring communities, which are even smaller in both population and area. Ins lies at the end of the Bienne-Täuffelen-Ins (BTI) rail line, and is also served by the Ins-Erlach postbus.

On 31 December 2009 Amtsbezirk Erlach, the municipality's former district, was dissolved. On the following day, 1 January 2010, it joined the newly created Verwaltungskreis Seeland.
