Alexandra Palace, designed by John Johnson and Alfred Meeson

John Johnson (1807 – 28 December 1878) was an English architect who specialised in religious buildings and churches in the Gothic style. He was regularly employed by the civil engineer Sir John Kelk to design the homes and public buildings Kelk funded. Johnson is best known for his collaboration with Alfred Meeson on designs for Alexandra Palace in north London; his designs for the Church of St Edward the Confessor in Romford, Essex; and for the Grade I listed St Mary's Church in Tidworth, Wiltshire, which was completed the year he died.

One of Johnson's churches – St Luke's Church, Euston Road – was bought by Midland Railway and dismantled to make way for St Pancras railway station. It was re-erected by Johnson in Wanstead where it became Wanstead United Reformed Church. Johnson's participation in the work gave him the distinction of becoming one of a small number of architects to have undertaken such a move and subsequent reconstruction.
