Country Bordering Both Peru and Venezuela: Colombia

Colombia is the only country sharing land borders with both Peru (southeast, ~1,600 km through Amazon) and Venezuela (north/northeast, ~2,200 km — longest border for both).

• Colombia–Peru: Amazon rainforest, Putumayo River, Leticia (Colombian Amazon capital)
• Colombia–Venezuela: Llanos (plains), Andes (Sierra de Perijá), Lake Maracaibo basin, Catatumbo region

Triple border: Colombia–Peru–Brazil meet at Amazon River (near Leticia/Tabatinga/Santa Rosa).

Colombia's unique position makes it the northern gateway to Amazonia and the Andean bridge to the Caribbean.
