Sixteen teams participated in the 2015–16 Cypriot Third Division. All teams played against each other twice, once at their home and once away. The team with the most points at the end of the season crowned champions. The first three teams were promoted to the
2016–17 Cypriot Second Division and the last three teams were relegated to the
2016–17 STOK Elite Division. However, after the end of the season
Nikos & Sokratis Erimis withdrew from the
2016–17 Cypriot Third Division, and so the 14th-placed team remained to Third Division.
Point system Teams received three points for a win, one point for a draw and zero points for a loss. ==Changes from previous season==
