Donnelly Boat Landing is a riverside launch site on the Donnelly River near Yeagarup, within the Shire of Manjimup in southwest Western Australia.

A concrete single-lane boat ramp with a boarding platform makes it straightforward to put in small motorboats, kayaks, and canoes. Access is via an unsealed red dirt road off Vasse Highway, reached by turning onto Boat Landing Road.

From the landing, paddlers and boaters can head downstream through jarrah forest as the river gradually widens across the coastal plain. Near the mouth, high limestone cliffs line the banks before the river reaches a sandbar.

Water depths and currents can vary considerably, and the river mouth is seasonally closed.

The waterway supports freshwater species including western minnow, western pygmy perch, black bream, and trout, along with a diversity of birds, mammals, and invertebrates along its banks.
