The land boundary between the Kingdoms of Jordan and Saudi Arabia, at 731 kilometers, begins in the north at the intersection of the border with Iraq. It then follows a series of six short, straight lines, including an abruptly concave portion of the border, referred to as “Winston’s Hiccup.” Originally drawn by Winston Churchill in 1925 during the first border delineation, the “Hiccup” was meant to account for the movements of the nomadic tribes within the area. The border was fully delimited in 1965, resulting in an exchange of territories in which Jordan was granted land along the Gulf of Aqaba to the south, and Saudi Arabia gained landlocked territory in the southwest. The terminal point of the land border, determined in the 2007 maritime boundary agreement, lies on the coastline of the Gulf of Aqaba.

Since the 1940s, Jordan and Saudi Arabia have had favorable diplomatic relations due to aligning political and religious views. There are no known modern-day border disputes between the two countries.
