Bousquet-Chavanne (pictured) will relocate to the Gulf at the start of August to take up the role.
He replaces Nasser Rafi, who will move to another role in the company.
Bousquet-Chavanne said: "Emaar Malls is one of the best mall operators in the world with outstanding customer focus and strong relationships with global brands across physical and digital retail.
"I am excited about their planned expansion and opportunities ahead."
Bousquet-Chavanne was previously executive director for customer, marketing and M&S.com. The restructure, announced in April, also saw the departure of marketing director, brand and customer, Rob Weston.
It left Nathan Ansell and Sharry Cramond, marketing directors for clothing & home and food & hospitality respectively, as the most senior marketers in the company.
