Yvonand is a municipality in the district of Jura-Nord Vaudois (former Yverdon) of the canton of Vaud in Switzerland.

In the Bronze Age, settlements were made of wooden stakes in Yvonand bay.

The area around Yvonand village was settled during the Roman era, on the road between Eburodunum (Yverdon) and Aventicum (Avenches).

At Mordagne to the west of the Mentue, the foundation walls of a Roman villa were excavated, which was established around 100 years after Christ.

The place name derives from the Germanic family name Evo and the word 'nant', which signifies a brook or a valley.

During the Burgundian Wars in 1476, Yvonand came under the administration of Grandson, which was itself under the common rule of Bern and Fribourg; situated at the southern lakeshore it had its own Court of Justice.

[5] Yvonand is 438 metres (1,437 ft) above sea level and 8 km (5.0 mi) east northeast of the former district capital Yverdon-les-Bains.

The village extends along the mouth of the River Mentue, briefly before its delta into Lake Neuchâtel, in northern French speaking Switzerland.

The central part of the area features the delta of the River Mentue, which flows into Lake Neuchâtel.

The lakeshore in the region of and surrounding Yvonand is flat, near a belt of reeds and forest.

In the southeast the land rises to its highest point, in the municipality, at 675 m (2,215 ft) above sea level, bordering a high plateau with Rovray and Arrissoules, achieving the height of La Baume, which then drops dramatically toward Yvonand.

The southern part of the municipality covers the valley of the Mentue, up to 1 km (0.62 mi) wide.

On the east side of the River Vaux, the stream has created a valley in the course of millions of years by its erosive strength.

[8] The historical population is given in the following chart:[3][12] In the 2007 federal election the most popular party was the SP which received 28.71% of the vote.

In the tertiary sector; 107 or 28.9% were in wholesale or retail sales or the repair of motor vehicles, 14 or 3.8% were in the movement and storage of goods, 32 or 8.6% were in a hotel or restaurant, 2 or 0.5% were in the information industry, 3 or 0.8% were the insurance or financial industry, 8 or 2.2% were technical professionals or scientists, 37 or 10.0% were in education and 130 or 35.1% were in health care.

This motorway runs across the heights to the south of Yvonand, where the deep valleys of the Mentue and the Vaux had to be spanned, with two impressive viaducts over 100m high (Pont sur la Mentue and Viaduc du Vaux).

On 1 February 1877 the Yverdon railway line was extended to Payerne with a station in Yvonand.

The recent extension of the A1 motorway, which traverses the municipality has improved communication links, making it more attractive to commuters, who work further afield, but who enjoy the sheltered lakeside location.

In the Vaud cantonal school system, two years of non-obligatory pre-school are provided by the political districts.
