This species grows in swamps and winter-wet areas in sandy clay in kwongan and is only known from near Byford, Serpentine and Elgin in the south-west of Western Australia.
Synaphea odocoileops is listed as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is known from only one or a few locations that are potentially at risk.
