Dalgety Bay (/dælˈɡɛti ˈbeɪ/ ⓘ) is a coastal town and parish in Fife, Scotland, on the north shore of the Firth of Forth, 9 miles from Edinburgh city centre.

The root of the place-name Dalgety is the Scottish Gaelic word dealg, 'thorn', and the full name originally meant 'the place of the thorn[-bushes]'.

[5] Dalgety Bay contains 9 Listed Buildings or structures by Historic Scotland, and features on the Fife Coastal Path.

During the First World War Morton Gray Stuart, 17th Earl of Moray donated a portion of his land to the Crown, which built an airfield there in 1917 as a base for the Royal Naval Air Service.

[13] In early 2014 the MoD made four proposals regarding how to deal with the contamination, ranging from erecting fences to keep the public out, to sealing it in with concrete.

[14] In September 2023, SEPA announced that the operation to remove the contamination had been successfully completed and that the relevant stretch of shoreline was now safe for public access for the first time since 2011.
