Droga, who quit his Publicis job in August this year to launch a joint venture called Drogafive, is associated with 45 Lions and two Grands Prix at Cannes.
Drogafive, a brand ideas and entertainment agency, launches next year with bases in New York and Los Angeles.
Droga, an Australian, said: "I am extremely flattered to be the jury president. Cannes has always been very good to me and I hope to reciprocate as much as possible."
Former jury presidents include TBWA's John Hunt and BBDO's Marcello Serpa.
