Army United Football Club (Thai: สโมสรฟุตบอลอาร์มี่ ยูไนเต็ด) was a Thai professional football club under the stewardship of the Royal Thai Army based in the Din Daeng District of Bangkok. It was one of the oldest football clubs in Asia, until it was discontinued at the end of the 2019 season after 103 years in existence.

The club was founded in 1916 and was known as Royal Thai Army until November 2010. Their home stadium was known locally as the Thai Army Sports Stadium and was more widely known around Asian circles as the Royal Thai Army Stadium, which had been host to numerous international youth matches due to its central Bangkok location. The club played in red shirts with red shorts and red socks. Despite finishing bottom of the Thai Premier League in 2010, they managed to regain their top-flight status after winning Group B of the Thai League Play-off in 2011.
