Cường Để (彊㭽, IPA: [kɨ̂əŋ ɗe᷉]; born Nguyễn Phước Dân (chữ Hán: 阮福民); 11 January 1882 - 5 April 1951) was an early 20th-century Vietnamese revolutionary and nationalist who, along with Phan Bội Châu, unsuccessfully tried to liberate Vietnam from French colonial occupation.

Prince Cường Để went in secret to Japan under the name of Minami Kazuo (南一雄) at the end of 1905, leaving a pregnant wife and two young sons in French Indochina.

The organization was encouraged by the victory of Japan over Russia in the Russo-Japanese War, and received financial support from Sun Yat-sen, Liang Qichao as well as Inukai Tsuyoshi and Kashiwabara Buntaro.

However, after the Franco-Japanese Treaty of 1907, French colonial authorities applied diplomatic pressure against Japan to suppress the organization and many of its members were deported by 1910.

Prince Cường Để then went to Beijing, where the Chinese warlord Duan Qirui offered financial support if he would start an uprising against the French in Indochina as leader of the 1911 Vietnam Restoration Organisation (Việt Nam Quang Phục Hội).

Returning to Japan, Prince Cường Để found help from the Pan-Asian movement, including Tōyama Mitsuru and was given a monthly allowance by his old friend Inukai Tsuyoshi.
