Nguyen Phuc Tan (Vietnamese: Nguyễn Phúc Tần/ 阮福瀕; 1620–1687) ruled the southern provinces of Vietnam from 1648 to 1687. Phuc Tan was one of the Nguyễn Lords who ruled south Vietnam from the city of Phú Xuân (modern-day Huế). During his rule, the Trịnh-Nguyễn War came to an end. During his reign, he annexed nearly all the remaining Champa lands. Phuc Tan was the second son of Nguyen Phuc Lan. Lan died just before Trịnh Tráng made yet another effort to conquer the southern provinces. Phuc Lan took the title Duong Quan-Cong (Duke of Duong).
