Vechigen is a municipality in the Bern-Mittelland administrative district in the canton of Bern, Switzerland. Until the administrative centralization of 1966, it was composed of four semi-autonomous communities: Vechigen, Sinneringen with Boll and Dentenberg, Utzigen with Lindental, and Berg with Littewil and Radelfingen.

Vechigen was first mentioned in 1275 as Vechingen. Sinneringen was first mentioned between 1261 and 1263 as Sineringen. Utzigen was referred to as Uzingen in 1275.

The Vechigen valley and mountain originally belonged to the Baron of Belp-Montenach. However, in 1298, they lost their land to the growing city of Bern. From then on, Vechigen was one of the four outer parishes of Bern, and until 1798, residents of the village were also citizens of the city.

The village church of St. Martin was first mentioned in 1275. It was rebuilt in 1513/14, and the bell tower dates from 1486.

In 1834, the municipality of Vechigen was formed with four quarters: Vechigen, Sinneringen with Boll and Dentenberg, Utzigen with Lindental, and Berg with Littewil and Radelfingen. Each quarter was responsible for local administration, including schooling and road construction, while the municipality handled taxation and finance. In 1913, the Worblentalbahn opened a rail station in Boll-Utzigen. By 1950, the agglomeration of Bern had expanded along this line, and the villages of Boll and Sinneringen became part of the agglomeration area. The population in these two villages grew rapidly, while it either dropped or stagnated in the rest of the municipality. As the quarters transitioned from agricultural to residential areas, the decentralized government became inefficient, leading to its centralization into a single government in 1966. In 1961, a secondary school was built in the municipality, and there are now a total of five school buildings.

Until 1966, the Sinneringen quarter included Sinneringen itself, the hamlets of Boll and Dentenberg, as well as farmhouses in the Worblen Valley and on Dentenberg Mountain. On the hillside above the Worblen, several Hallstatt graves were discovered, and a Roman villa was found at Hubel. During the 13th century, the Counts of Kyburg were the vogts of the village. In 1729, Hans Rudolf von Diesbach built his country estate, the Schlössli, in Sinneringen. In 1844, the artist August von Bonstetten expanded the manor house and added a clock tower.

By the 1950s, Sinneringen had become part of the Bern agglomeration, leading to a rapid population increase. By 2005, more than half of Vechigen's population lived in Sinneringen and Boll.

Boll developed from shops and inns located at the intersection of the Bern-Krauchthal and Worb-Zollikofen roads. In the 18th and 19th centuries, it consisted of a customs station, an inn, a smithy, a sawmill, and a few houses. During the 19th and 20th centuries, nearby rivers were redirected, and local swamps were drained, opening up new land around Boll for housing and farming. Despite 19th-century road construction and the completion of the Worblentalbahn rail station at Utzigen-Boll in 1913, Boll remained a small village. However, during the 1960s, the outskirts of Bern reached Boll, leading to rapid expansion. Today, the majority of Boll’s residents commute to Bern for work.

The Utzigen quarter included the village of Utzigen, the hamlets of Wuhl, Birchi, and Lindental, as well as 50 houses situated on a hillside above the Worblental. Utzigen originated from a late medieval herrschaft. Beginning in the 14th century, it was owned by several Bernese patrician families and was administered from Utzigen Castle. In 1669, Samuel Jenner (1624–1699) built a new castle on the site of the earlier building. After the 1798 French invasion, the herrschaft was dissolved. The Dachselhofer family, who owned the estate in 1798, lost their rights to hold the low court over the herrschaft but retained the castle and other property. The castle served as the family's summer residence until 1875, when it was sold to the municipality. The municipality then established an institute for alcoholics and unemployed men and women. At its peak, the institute housed over 500 people who worked on the large farm attached to the estate. In 1964, the castle was converted into a nursing and retirement home, and in 2001, it became a residential care home. The village also has a primary school.
