Lawrenny is a village and parish in the community and electoral ward of Martletwy in the county of Pembrokeshire, Wales.

The village extends down to the Estuary to Lawrenny Quay half a mile from the centre, where there is a busy yacht station and caravan park.

It provides most of the central rural facilities for the Martletwy ward, mobile post office, cricket and football clubs, village hall and church.

The Lawrenny Arms and the Quayside Tearooms have recently become popular destinations in the area for both boaters and walkers.

[3] Racing stables in the village provided Wales' first and only Grand National winner,[4] Kirkland, at Aintree in 1905.
