John G. Kincaid & Company was a leading British producer of marine engines, situated at the estuary of the River Clyde in Greenock, Inverclyde, Scotland.

The firm's origins trace back to 1868 with the establishment of Hastie, Kincaid and Donald, founded by John Hastie, John Kincaid, and Robert Donald. Following Hastie's departure in 1871, the business was rebranded as Kincaid, Donald & Co. When Robert Donald exited in 1881, John Kincaid renamed the enterprise Kincaid & Co.

In 1888, the company became a limited liability corporation and later reorganized as a partnership named John G. Kincaid & Co in 1895, involving John Kincaid and his brother Charles. It returned to limited liability status in 1906 and transitioned into a public company by 1937.

After the Second World War, the company experienced a downturn that mirrored the decline of British shipbuilding. Nationalised in 1977 under the Aircraft and Shipbuilding Industries Act 1977, it merged with Clark-Hawthorn in 1978 to create Clark Kincaid. Subsequently, British Shipbuilders sold it for a nominal sum of £3 through a management buyout to HLD Holdings. In 1990, ownership transferred to Norway's Kvaerner Industrier, adopting the name Kvaerner Kincaid. The firm shifted its focus to manufacturing diesel engine parts before being sold in 1999 to Sweden's Scandiaverken AB for several hundred thousand pounds. Manufacturing operations ceased thereafter, with the company functioning solely as a distribution centre for marine engine components.
