Ucingo olunameva(ebizwa nangokuthi i-barb wire) uhlobo lwentambo esetshenziswa ukwenza uthango olushibhile. Inezinsika zensimbi ezibukhali (ama-barb), okwenza kube nzima futhi kube buhlungu ukukhwela phezu kwayo. Ucingo olunezinsika lwasungulwa ngo-1867 e-United States nguLucien B. Smith. Ucingo olunezinsika lungasetshenziswa amazwe amaningi empini, emajele, ezindlini zokuboshwa, ezakhiweni zikahulumeni nakwezinye izikhungo zokuphepha kwezwe.
