Alison Reef (Filipino: Bahura ng De Jesus; Tốc Tan Reef (Vietnamese: Đá Tốc Tan); Mandarin Chinese: 六门礁; pinyin: Liùmén jiāo) is a reef on the Spratly Islands in the South China Sea. The reef has been occupied by Vietnam since 1988. It is also claimed by China (PRC), the Philippines, Vietnam, and Taiwan (ROC).[1][2][3]

In early December 2022, Vietnam began dredging and filling activities at the Tốc Tan A island site.[4] By November 2023, Tốc Tan A had become an artificial island with an area of approximately 2 hectares, a length of about 150 meters, and a width of about 140 meters. Vietnam began filling and dredging at the Tốc Tan C island site in September 2024, and at the Tốc Tan B island site in December 2024. The three islands together total 6 hectares.
