Alfred Wurzbach Ritter von Tannenberg (born 22 July 1846 in Lemberg; died 18 May 1915 in Vienna) was an Austrian art critic.
He was the son of Constantin von Wurzbach. He studied jurisprudence in Vienna and entered the civil service, but resigned in 1876 and devoted himself entirely to the study of art history. He was art critic for the Wiener Allgemeine Zeitung from 1881 to 1886.
Under the title Zeitgenossen he published a series of biographical sketches (1871-72), and afterwards the monograph Martin Schongauer (1881), a Geschichte der holländischen Malerei (History of Dutch painting, 1885), besides biographies of Dutch and Flemish painters in Dohme's Kunst und Künstler (Art and artists, 1876). He also edited the éditions de luxe of Die französischen Maler des achtzehnten Jahrhunderts (French painters of the 18th century, 1879-80), Die goldene Bibel (The golden Bible, 1880), and Rembrandt-Galerie (1885), and translated Houbraken's Groote schouburgh der nederlandsche konstschilders (The Great Theatre of Dutch Painters, 1879; original Dutch edition 1718).
