Edward John McCoy ONZM (23 February 1925 – 17 January 2018), generally known as Ted McCoy, was a New Zealand architect whose practice was based in Dunedin.^[1] He designed the sanctuary of St Paul's Cathedral (completed 1970), and the Richardson (formerly Hocken) Building of the University of Otago (completed 1979), among many others. In 1950, he established McCoy and Wixon Architects, joined in partnership by Peter Wixon in 1967.

Born on 23 February 1925,^[2] McCoy studied architecture at the University of Auckland, graduating in 1949. He moved back to his home city of Dunedin the following year, setting up an architectural practice in the city. His first major design was for the Dominican Order's Aquinas Hall, in the north of the city, (now an Otago University hall of residence, Aquinas College). The design won a Gold Medal as design of the year from the New Zealand Institute of Architects.^[3]

McCoy and his wife Nola had 13 children, two sons and 11 daughters, four of whom followed him into architectural design.^[3] He died at his home in Dunedin on 17 January 2018, aged 92.^[4]
