Pleasure Bay is an estuary in Monmouth County, New Jersey, and a tributary of the Shrewsbury River. It begins where Branchport Creek and Troutmans Creek join, then flows north toward the river, with Manahasset Creek entering shortly before its mouth. The bay also functions as a local boundary, separating Oceanport from Long Branch and Monmouth Beach. As part of this setting, it belongs to the interconnected tidal waterways that shape this section of the New Jersey coast.
