William Fuller Pocock (1779 – 29 October 1849) was an English architect.
His first essays in art were landscape-paintings; but at the age of twenty he had begun to work as an architect.
The headquarters of the London militia, Bunhill Row, were designed by him; the Wesleyan Centenary Hall in Bishopsgate Street Within (1840); Christ Church, Virginia Water; and a great number of smaller works.
Pocock died on 29 October 1849 in Trevor Terrace, Knightsbridge, London.
He published: His son William Willmer Pocock was also an architect.
