The Landing at Kesang River was an amphibious raid conducted by a small force of Indonesian volunteers near the Kesang River, on the border between the Malaysian states of Malacca and Johore on the southwestern part of the Malay Peninsula. The landing was part of the broader Indonesia-Malaysia confrontation, an undeclared war fought between Malaysia and Indonesia during the early 1960s over the creation of an independent Malaysian Federation. The conflict chiefly encompassed parts of northern Borneo, areas that Indonesia sought control in her bid to increase her power and influence in Southeast Asia; however, the landing represented a shift of the operational sphere toward the mainland.
