Delta Raya Sidoarjo Football Club is an Indonesian football club based in Sidoarjo, Indonesia. Founded in 1989 by a businessman named HM Mislan as Gelora Dewata '89 with home base in Bali, they moved to Sidoarjo in 2001 and changed their name to Gelora Putra Delta after playing some matches in the early 2001-2002 season. Some time later, still in 2001, they became Deltras as acronym to Delta Putra Sidoarjo.
In 2003, the ownership status of the club changed from HM Mislan to the Government of Sidoarjo Regency, making Deltras another official football club of Sidoarjo after Persida Sidoarjo. In 2011, after the club's financial problem during the 2010-2011 season, the Government of Sidoarjo Regency established PT Delta Raya Sidoarjo, a limited liability firm owning Deltras Sidoarjo to fully professionalize the club's management.
The establishment of the firm in 2011 brought a great deal of change to the club. In late 2011, the club's management decided to change the club's name from Deltras Sidoarjo, to Deltras F.C. The term Putra in Delta Putra Sidoarjo which means Son was changed to Raya which means Great, Large.
The club's home stadium is the Gelora Delta Sidoarjo.
