Stanisław Konstanty Pietruski (11 March 1811 – 28 January 1874) was a Polish zoologist and horticulturist who studied the fauna of the Carpathian region and founded the first private zoological garden in his estate in Podhorodce (Skolew region) in 1833.
A fire in 1848 destroyed his zoo after which he spent time in horticulture in his estate.
He also took an interest in the fishes and insects of the Galician region.
He corresponded widely with other zoologists in Europe including Alfred Brehm, Lorenz Oken, Rudolf Kner and Maksymilian Nowicki.
He lived towards the end of his life at his sister's estate in Podhajecki.
