Jones & Willis was a Birmingham-based stained-glass firm active from the mid-nineteenth century into the early twentieth century. The partnership was established by John Jones and William Willis and became known for ecclesiastical glazing across England and Wales.

The firm produced windows in a refined Gothic Revival idiom, characterised by clear narrative structure, strong figure drawing, and balanced colour harmonies. Their work frequently includes carefully integrated scriptural inscriptions and emblematic tracery lights, reflecting the didactic emphasis typical of late Victorian church decoration.

Jones & Willis operated within the broader Midlands network of stained-glass manufacture and shared stylistic affinities with firms such as Hardman and Clayton & Bell ⓘ, while maintaining a distinct clarity of composition and disciplined ornament.

Their windows often combine narrative scenes with symbolic upper tracery — Agnus Dei, doves, evangelist symbols, or scriptural mottoes — reinforcing theological themes within architecturally ordered compositions.
