Turner House Gallery is an art gallery in Penarth near Cardiff, Wales.
The gallery was built in 1887/8, designed by architect Edwin Seward in a Queen Anne style for the rich local flour merchant, James Pyke Thompson. Pyke Thompson used the gallery to exhibit his collection of J.M.W. Turner paintings (hence the name of the gallery) with free entrance to the public.
Turner House Gallery was acquired by the National Museum of Wales in 1921 and used to display the museum's secondary public art collection.
The building was given Grade II listed status in 1993.
In 2003 Turner House was taken over by the registered charity, Ffotogallery, and has subsequently been used for photography-based exhibitions. In 2014/15 the gallery became part of a wider Artes Mundi exhibition, staging works by Icelandic artist Ragnar Kjartansson and Croatian artist Sanja Iveković for Artes Mundi 6.
