Early history
Siuntio has been inhabited since the Stone Age, with the oldest evidence of farming settlements discovered in the river valley around the medieval Siuntio church. Many Bronze Age burial sites can also be found in Siuntio, such as Krejansberget hill and Luntoberget hill near St. Peter's Church. Some Iron Age sites, like Ekeberga Burial Site, are also found in the municipality. Apart from burial sites also a prehistoric hill fort, Skällberget, is found opposite to the church. The oldest known document mentioning Siuntio is from 1382. The document addresses a donation to the Church of St. Lawrence in Lohja.

The Middle Ages
During the Middle Ages two large manor houses, Suitia and Sjundby, were built in Siuntio.

The earliest mention of Suitia Manor is from 1420 in a document addressing a border conflict between Suitia estate and an estate owned by the bailiff of Häme Castle. Later, the estate came to the possession of the Fleming family. Over time, the Flemings acquired new land for the Suitia estate; at one point, Suitia had its own harbor by the sea near the mouth of Pickala river. The Flemings also built the first ironworks in Finland, located on the grounds of Suitia Manor, in the 1530s.

The Sjundby Manor House is first mentioned in a document from 1417. The manor was owned by a number of nobles and royals, including Queen Christina of Sweden.

The stone St. Peter's Church was built around 1480 on the site of previous wooden church buildings. The sacristy, the oldest part of the church, and armory were removed after the church caught fire in 1823.

1800–2000
The National Author of Finland, Aleksis Kivi, lived in Siuntio in Fanjunkars croft from 1864 to 1871.

The old municipality center around the church started to lose its significance after the coastal railway was built. The new railway station was built a few kilometers south of the church, which resulted in the creation of the new municipal center around the railway station.

After the Second World War, parts of Southern Siuntio were leased to the Soviet Union as part of the Porkkala Naval Base for 50 years following the 1944 Moscow Armistice between Finland, the Soviet Union and the United Kingdom. Although the land was returned to Finland in 1956, signs of Soviet occupation can still be found around the area, including military orders written in Cyrillic script on the walls of the dairy house of the Sjundby Manor House and a Soviet Triumphal Arch near Pickala Manor House.

2000–present
In 2011 Siuntio, together with the municipalities of Karjalohja, Sammatti and Nummi-Pusula, decided to merge with the city of Lohja starting in 2013. The decision was made following encouragement from the Finnish State to merge smaller municipalities together. The goal was to create larger administrative areas to eventually cut costs. However, the decision caused a conflict between the Siuntio political parties, which also divided the population. After several unclear negotiations, Siuntio failed to deliver any kind of answers and therefore was cut out of the merge with Lohja.

In 2018 Siuntio joined the Helsinki Regional Transport Authority, securing good public transportation connections to Helsinki sub-region.

The northern part of Siuntio has many high hills and a large esker covered in forest, while the southern part of Siuntio is less hilly but also covered in forests.

Sjundby was on the Soviet side of the border during the Soviet lease of Porkkala Naval Base. During this period, the house was badly damaged but was eventually restored.

Pickala Manor House and Soviet Triumphal Arch

Near the manor house runs a cobblestone road, known as the Kabanov's road, which runs from Pickala to a Soviet triumphal arch, the only surviving Soviet Triumphal arch in Finland. The road was paved with cobblestone to make it strong enough for Soviet military vehicles to drive on. Pickala Manor House and its surroundings are listed as Nationally Significant Built Cultural Environment and protected by the Finnish Heritage Agency.
