The Haikou Ring Expressway (), designated as G98 and Hainan Provincial Expressway S82, is a in Haikou, Hainan, China.
Opened on 6 August 2008, it is now part of G98 (Haikou section, connecting the original East-West Expressway). The second phase of the project G98<small>12</small> (Meilan Airport Interchange-Yanfeng Interchange) was opened to traffic on 21 September 2019.
The expressway originally had the G15<small>01</small> route marker until 2017 when it was renumbered as the G98<small>01</small>. In July 2022, the G98<small>01</small> designation was officially removed, along with a number of other ring roads of coastal cities in the NTHS, because Haikou is a coastal city and it would be inefficient to route a brand new expressway into the sea for no reason.
