Baltray (historically Ballytra, from Irish: Baile Trá, meaning "beach settlement") is a village and townland in County Louth, Ireland. It sits on the northern shore of the River Boyne estuary.

The village has developed since the latter half of the twentieth century as a dormitory village serving Drogheda Town, which is located inland, to the west of Baltray. It has a general store and a public house.

Baltray is well known for the Golf Links and the "Baltray standing stones", a group of megaliths.

Baltray is home to the Little Tern Conservation Project which is run by *Louth Nature Trust. The project began in 2007 and runs each year from May to August when part of the beach at the Haven is fenced to protect nesting Little Terns. These birds are an Annex 1 species under the EU Birds Directive (79/409/EEC), thus EU member states are required to take special conservation measures to ensure that little terns remain at a favourable conservation status. There is a huge volunteer effort by the local community to warden the project.
