The Creeperopolis–Salisford border (Creeperian – Creeperian: ֆրոնտերա Ծրեեպերօպոլիս–Սալֆորտո; Creeperian – Iberic: frontera Creeperópolis–Salforto; Salisfordian: confine Creeperopola–Salforto) is an international border separating Creeperopolis and Salisford. The entire border is defined by the Rubicon River. The two countries acquired a land border with each other after Creeperopolis annexed the Kingdom of Castilliano in December 1949, with Creeperopolis and Salisford retaining the Rubicon River as the border between the two countries.
In 1961, Creeperopolis and Salisford went to war regarding a border dispute, with Salisford arguing that it deserved to annex land east of the Rubicon River. The two countries signed the Rubicon Agreement on 22 April 1976 to end the war and restored the status quo ante bellum, agreeing to maintain the Rubicon River as the border between both countries. The border with Salisford is Creeperopolis' second shortest land border, spanning 454.3 miles (731.2 kilometers) from the Sea of Castilliano to the Salvadoran border.
