All Saints' Church is the parish church of Upper Poppleton, a village in the rural north-western part of the City of York district, in the ceremonial county of North Yorkshire, England.

[3] The original church was demolished in 1890, and replaced by a new building, designed by C. Hodgson Fowler, which was completed the following year.

The vestry is on the north side, and it is linked to the church by a connection designed by George Pace and built about 1964.

Inside, the roof structure is wooden and is prominent, its trusses alternating in design.

The font is 13th century and has an octagonal stem and a plain stone bowl.
