Parc Gwyliau Ynysymaengwyn (Ynysymaengwyn Caravan and Camping Park) is a local authority-owned holiday and touring park set within the grounds of a historic manor house and adjoining woodland near Tywyn, Gwynedd, in North Wales.

The site accommodates touring caravans, motorhomes, and tents of all sizes, along with a number of privately owned static caravans.

Modern facilities are complemented by the tranquil, historic character of the estate, with small woods and direct access to local footpaths on-site.

The park is well placed for a wide range of outdoor pursuits, including walking, cycling, climbing, fishing, and water sports. The Talyllyn narrow-gauge railway is a short drive away, and Tywyn town centre is nearby.

The site has received a Green Flag Award, recognising it as a quality green space. It operates seasonally, opening from April through October.
