1186 Turnera, provisional designation 1929 PL, is a main-belt asteroid discovered on August 1, 1929, by Cyril Jackson at Johannesburg Union Observatory in South Africa. The relatively bright, stony S-type asteroid measures about 36 kilometers in diameter.[1]

Turnera is named in honor of the British astronomer Herbert Hall Turner (1861–1930), director of the Oxford University Observatory.[2] He is also credited with coining the term "parsec".
