't Zandrak is a private marina on the Hollandsche IJssel in Capelle aan den IJssel, South Holland. Its 115 moorings are individually owned and vary in size from 9 by 4 metres up to 24 by 7 metres; some owners make their berths available for rent.

The marina is managed by the Owners' Association Marina 't Zandrak, with the board and harbour master roles filled by volunteers. Access is restricted to berth owners and renters — the marina is not open to passing boaters.

Land-side moorings are reached through a locked gate operated by a key tag. The site sits directly on the Hollandsche IJssel, which forms part of the Staande Mast Route and offers good waterway connections toward Rotterdam and Gouda.
