The Hermitage Douglas-fir (also known as Ossian's Douglas-fir) was a Douglas-fir tree which stood in The Hermitage pleasure ground, in Dunkeld, Scotland, between c. 1887 and 2017.

It was the second tree (after a grand fir in Argyll) in Britain to reach 200 feet (61 m) in height, in 1980. It eventually reached a height of 63 metres (207 ft) in 2009 before it was blown over due to high winds in the early hours of 13 January 2017. It was a self-sown tree, growing from seed blown from one of three older trees at the Hermitage, and was found by increment boring to have germinated around 1887.
