The St. Martin River is a tributary of Isle of [Wight Bay] in Worcester [County, Maryland]. Approximately long, it drains the northernmost part of Worcester County.
A short river, the St. Martin broadens rapidly to enter Isle of Wight Bay where the bay is crossed by Maryland Route 90. Most of the river is a tidal estuary. Its two main tributaries are the Bishopville Prong and the Shingle Landing Prong.
The St. Martin forms the northern boundary of Ocean [Pines, Maryland]; Bishopville, Maryland is on the Bishopville Prong of the river.
