The Western Nigeria Security Network (WNSN), codenamed Operation Àmòtékùn (Yoruba for "Leopard" or "Cheetah") and simply known as the Àmọ̀tẹ́kùn, is a security outfit based in all the six states of the South Western, Nigeria, responsible for curbing insecurity in the region.

It was founded on 9 January 2020 in Ibadan, Oyo State, Nigeria as the first regional security outfit initiated by a geopolitical zone in Nigeria.

The Osun State Executive Council approved a bill for the establishment of the Osun State Security Network Agency and Àmòtékùn Corps. It also directed that the bill be forwarded to the State House of Assembly for legislative processing and subsequent passage into law.
