St Oswald's Church is in the village of Backford, to the northwest of Chester, Cheshire, England, close to the A41 road and adjoining Backford Hall. It is recorded in the National Heritage List for England as a designated Grade II* listed building. The church dates from the 14th century with later additions and restorations. It contains one of the few surviving aumbries in Cheshire and a number of memorial boards painted by the Randle Holme family. It is an active Anglican parish church in the diocese of Chester, the archdeaconry of Chester and the deanery of Wirral South. Its benefice is combined with that of Holy Trinity Church, Capenhurst. From March 2018 this benefice shares a vicar with All Saints, Saughall.

Randle Holme was a name shared by members of four successive generations of a family who lived in Chester, Cheshire, England from the late years of the 16th century to the early years of the 18th century. They were all herald painters and genealogists and were members of the Stationers' Company of Chester. All four painted memorial boards and hatchments, and some of these can still be found in Cheshire churches.
