Ranger's House is a medium-sized red brick Georgian mansion in the Palladian style, adjacent to Greenwich Park in the south east of London. It is situated in Blackheath and backs directly onto Greenwich Park. Presently there is a rose garden behind it. Since 2002 it has housed the Wernher Collection of art.

The house dating from c.1700, was originally built built by Capt., later Vice-Admiral Francis Hosier(1673–1727), on wasteland adjacent to Greenwich park. The House then had a superb view and easy access to London by road and river. Admiral Hosier occupied the house from 1700-1727. He had made his fortune through trade at sea and both the ship he served on as a lieutenant and his own ship were called the Neptune. Hosier died of yellow fever at sea in 1727, during the disastrous Blockade of Porto Bello off Panama.

In 1748 the lease of the house was inherited by the 4th Earl of Chesterfield. He was a politician, diplomat, man of letters and wit who eventually became Secretary of State. He added the splendid bow windowed gallery for entertaining and displaying his art treasures. Chesterfield wrote that the view from the gallery gave him "three different, and the finest, prospects in the world".
