Treales, Roseacre and Wharles is a civil parish in the Borough of Fylde, Lancashire, England. It had a population of 492 at the 2011 Census. It lies two miles east of Kirkham and includes the villages of Bolton Houses, Moor Side, Roseacre (/ˈrɒzəkər/), Treales (/treɪlz/) and Wharles (/hwɔːr.ləz/).

The village was called "Treueles" in the Domesday Book and "Turuel" in 1242. At the time of the Norman invasion of England, it was held by Earl Tostig. It later came into the possession of the Earl of Derby.

In Treales the Anglican parish church, Christ Church, is situated on Church Road. It was built in 1855 by Lord Stanley, when the Patron was the vicar of Kirkham. The church is now part of a benefice with Christ Church, Wesham. The Derby Arms public house is situated on the corner of Kirkham Road and Church Road. The village has a windmill, now converted to a private dwelling.

The village is called "Quarlous" in 1249 and "Warlawes" and "Werlows" in 1286.

Wharles is the venue for the annual Fylde Vintage and Farm Show, which takes place in a field next to the M55 motorway.

The village is called "Rasaker" and "Raysakur" in 1249.

In February 2019, the government refused planning permission for fracking at Roseacre Wood. The application, by energy firm Cuadrilla, had been refused by the local council and was the subject of a public inquiry. The secretary of state said highway safety issues had not been "satisfactorily addressed" and refused planning permission.
