Isopogon fletcheri, commonly known as Fletcher's drumsticks,[2] is a species of flowering plant in the family Proteaceae and is endemic to a restricted area in the Blue Mountains of New South Wales.

[5] Isopogon fletcheri was first formally described in 1894 by Ferdinand von Mueller in Proceedings of the Linnean Society of New South Wales Series from specimens collected by Joseph James Fletcher from Blackheath, overlooking the Grose Valley.

[6][7] Fletcher's drumsticks grows in forest within the spray zone of waterfalls near sandstone cliffs in a few places near Blackheath.

[5] This isopogon is classified as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Government Biodiversity Conservation Act 2016.

The main threats to the species include its small population size, restricted distribution, disease caused by Phytophthora cinnamomi, disturbance due to walkers and rock climbers, and weed invasion.
