Yat Sen (Chinese: 逸仙, Pinyin: Yi Xian), named after the founding father Dr. Sun Yat-sen of the Republic of China and completed in 1931, was a light cruiser— having more in common with the small cruisers of pre–World War I era—in the ROC Navy before World War II. An enlarged design was laid down but never completed due to the Japanese occupation of Kiangnan shipyard.
