History A Hallstatt era grave was discovered in Dorigny. Three Bronze Age graves were found in Valeyre and several La Tène culture graves have been found in Bassenges and Valeyre. A motte (a raised earthen, fortified hill) of an unknown age is found at a place in the municipality which is known as Chateau-de-la-Motte.

Écublens is first mentioned around 958-59 as in villa Escublens. In 964 it was mentioned as Scubilingis in a document recording the property of the cathedral of Lausanne. This document mentions that Scubilingis is situated near Renens.

In the 10th century Écublens was part of the territory of Renens. Under Bernese rule it was part of the bailiwick of Lausanne and was administered by that court. In 1156, a chapel was built in Écublens which was under the authority of the Priory of Saint-Sulpice. In 1228 the parish church of St. Peter is first mentioned. By 1453 the parish church was again under the authority of the church of Saint-Sulpice.

On 9 May 1476, Charles the Bold, the Duke of Burgundy, gathered his army in Écublens after his defeat at the Battle of Grandson, in preparation for the Battle of Morat. The area was under the Bernese Occupation from 1536 until 1798, when French troops arrived. On 12 May 1800, Napoleon inspected two divisions of his troops in Écublens on his way to the Great St Bernard Pass during his Italian campaign of 1800.

In 1803 it was made the district capital. In 1909 the General Council was replaced by a local council.

During World War II a small aerodrome was operated in Écublens. As part of the nation's planning for post-war development of aviation, Lausanne planned to expand this facility into one of five regional airports forming a second-tier of airports in the country. This development would permit the disposal of the nearby Blécherett Aerodrome as that location was deemed to be unfeasible for expansion. This plan was not fulfilled, and the Écublens aerodrome fell into disuse. There was an effort in the 1950s to revive the plan and build an 1100 m runway along with facilities for regional and air taxi operations as the Lausanne-Ecublens Regional Airport (). A two-stage proposal foresaw paving at least one of the smaller grass surface runways as well to support recreational and executive use, but ultimately this plan as well was shelved.
