Richard Child, 1st Earl Tylney (5 February 1680 – March 1750), was an English politician who sat in the House of Commons between 1708 and 1734. Initially a Tory, he switched to supporting the Whigs after 1715. He held no Office of State, nor any commercial directorship of significance, but is remembered chiefly as the builder of the now long-demolished Palladian "princely mansion" Wanstead House, one of the first in the style constructed in Britain. In the furnishing of his mansion Child became the main patron of the Flemish painter Old Nollekens. He died in March 1750 aged 70 at Aix-en-Provence, France, and was buried on 29 May 1750 at Wanstead.
