Which countries share borders with Sri Lanka?

Because Sri Lanka sits entirely within the Indian Ocean, the island doesn't share physical land borders with any neighbours. Coastal waters ring the whole country, so you won't find any connecting land routes.

Despite this, the nation has significant maritime boundaries. If you look to the northwest, a sea border divides Sri Lanka and India, separated only by the narrow Palk Strait and the Gulf of Mannar. Then, to the southwest, a similar marine boundary exists with the Maldives. These shared waters ultimately make India and the Maldives the closest geographical neighbours to the island.
