Edward Haycock Sr. (29 July 1790 – 20 December 1870) was an English architect renowned for his work in the West Midlands and central and southern Wales during the late Georgian and early Victorian periods.

Around 1845, he transitioned from building contracting to focus solely on architecture, with his son Edward Haycock Junior (1829/30-1882) later joining the practice and continuing it until about 1880.

[3] "Haycock Way", linking Shrewsbury's 20th century inner ring road to the Column roundabout at Abbey Foregate, is named after the family.

Haycock was part of a group of architects, including Thomas Farnolls Pritchard, Joseph Bromfield and John Carline, who established Shrewsbury as a major centre for architectural innovation in the later 18th and first half of the 19th century.

In 1833, Samuel Lewis's “Topographical Dictionary of Wales” records “Upwards of thirty new leases have been granted, pursuant to which several houses have been already built, and others are already in progress; a general post-office, a posting-house and an excellent hotel have been established".

A newspaper obituary states Haycock also "obtained first prizes for plans for the Birmingham and New Orleans Infirmaries"[17] but these are not mentioned by Colvin.
