Colombia–Venezuela border
The Colombia–Venezuela border is an international border of 2219 kilometers (1378 mi) between Colombia and Venezuela, with a total of 603 milestones that demarcate the line. It is the longest border of both Colombia and Venezuela.

The border, at least in its terrestrial part, was essentially demarcated by two treaties: the Spanish Arbitration Award of Queen Maria Cristina of 1891 and the Treaty of Limits and River Navigation of 1941. But the definition of the border in the Gulf of Venezuela is still disputed, causing diplomatic clashes between the two countries.

In August 2015, two Venezuelan soldiers were injured during a fight with alleged Colombian smugglers, prompting Venezuelan President Nicolás Maduro to close a large part of the border, except in Táchira.
