Byng Inlet, inlet on Georgian Bay, Ontario, Canada

Byng Inlet is a widening of the Magnetawan River near its mouth, on the eastern shore of Georgian Bay between Parry Sound and the mouth of the French River. The Ojibwe name of the river, meaning "long open channel", refers to this stretch of water.

Byng Inlet was named by Captain Henry Wolsey Bayfield, who charted the Canadian shores of lakes Huron and Superior and made his headquarters at the Naval Establishment at Penetanguishene in 1819. Bayfield returned to England in 1825 to prepare his charts for the engraver. On November 10, 1898, the steamship Northern Belle was engulfed in a fire in the inlet; its wreck is now a site for recreational divers.

The inlet bears the name of Royal Navy Admiral John Byng, chosen during Henry Wolsey Bayfield's surveys of Georgian Bay in the early 1800s.

The inlet is easily accessible from inland routes and connects several local communities together. Visitors should be aware that water conditions vary greatly depending on the season.

The steamship Northern Belle burned in Byng Inlet on 10 November 1898; its wreck now draws recreational divers. The inlet's name honours John Byng, given by Captain Henry Wolsey Bayfield, who charted these shores and headquartered at the Penetanguishene naval establishment in 1819.
