Tan Hong Boen, commonly known by his pen name Im Yang Tjoe, was a Chinese Indonesian writer, journalist, and translator active in the Dutch East Indies and Indonesia from the 1920s to the 1950s. He also published occasionally under the pen names Madame D'Eden Lovely for romantic novels, Kihadjar Dharmopralojo for historical novels, and Kihadjar Soekowijono for Wayang stories. In 1933 he published a biography of Sukarno, whom he had shared a jail cell with in 1932; it seems to be the earliest known biography of Sukarno.
