St John the Evangelist's Church is in the small village of Byley, Cheshire, England. It is recorded in the National Heritage List for England as a designated Grade II listed building. It is an active Anglican parish church in the diocese of Chester, the archdeaconry of Chester and the deanery of Middlewich. Its benefice is combined with that of St Michael and All Angels, Middlewich. The architectural historian Nikolaus Pevsner regarded it as being "really very ugly" with a "minimum of motifs, but a maximum of materials".
