The Panama Canal is a man made body of water that connects the Atlantic Ocean with the Pacific Ocean.
It's a strait. Like the Straits of Magellan links the Atlantic Ocean and the Pacific.
If you mean the most narrow navigable "passage" then it's the Panama Canal, given the Pacific Ocean flows into the canal, then exits into the Caribbean Sea, which flows into the Atlantic. If you mean a natural "opening," then it's the "Drake Passage." From one source: "This opening connects the Pacific and Atlantic oceans and encircles Antarctica in a ring of cool water known as the Antarctic Circumpolar Current" (See related links below).
The Atlantic Ocean is connected to the Pacific Ocean through a narrow canal called the Panama Canal. From the Caribbean Sea on the Atlantic side, the canal cuts through Panama, to the Pacific Ocean.
