Michel-Ange Duquesne de Menneville, Marquis Duquesne (c. 1700 – 17 September 1778) was a French Governor General of New France. He was born in Toulon, France.

Duquesne served from 1752 to 1755. Best known for his role in the French and Indian War, he established Fort Duquesne in 1755 at the confluence of the Allegheny and the Monongahela Rivers at what is now Pittsburgh, Pennsylvania, was named after him. It was abandoned by French forces in 1758 with the arrival of the much more powerful British Forbes Expedition, which erected Fort Pitt in its place.

He built a line of defensive fortifications to strengthen the French presence. He later returned to France.

In 1758, he led a French squadron out of Toulon, intended to relieve another French squadron which had been sailing to Louisbourg to provide relief to the defenders there, but had been forced into Cartagena in neutral Spain. However, Duquesne was attacked by a British force led by Henry Osborne and two of his ships were captured, including his own flagship. The ultimate result of the action was to deny Louisbourg any chance of relief, and it surrendered later in the year.

He died in 1778 in Antony, Hauts-de-Seine.

Duquesne University was named after him.
