Jean de Lauzon or de Lauson (French pronunciation: ?[??~ d? loz?~]; 1584 – 16 February 1666) was the governor of New France from 1651 to 1657, one of the most challenging times for the new colony.
As a prominent lawyer in France, in 1613 Lauzon was appointed a counsellor in the Parliament.
He moved with his three sons – including François, the eldest, who was a member of Parliament for Bordeaux – to the colony.
His wife had apparently earlier died in France.
All three sons married into other founding families of the colony after having been set up with various lands and positions within the area.
The establishment of Lauzon's family in the colony was probably intended to inspire confidence amongst the settlers and encourage agriculture in addition to the fur trade.
He was the first governor to pursue this type of policy.
In 1653, Lauzon negotiated a peace treaty with the Mohawk, an Iroquois nation based in what is now New York.
It ended their attacks on French settlers and reduced the threat to the colony for some years.
Afterward, he accorded to himself the monopoly on the fur trade; settlers sought to open the trade by petitioning King Louis XIV.
The king responded by ordering the fur trade to be reopened to all colonists.
Lauzon returned to France, where he continued his business and political career.
He died in 1666 at the age of 83, in Paris.
One of his descendants, Marie-Catherine-Antoinette de Lauson, married Roland-Michel Barrin de La Galissonière (1747–1749), who also served as Governor of Canada.
Lauzon, Quebec was named in his honour in 1867.
