Frederick Juengling (born Friedrich Jüngling, 8 October 1846 – 31 December 1889) was an American wood engraver and painter.
He was a founder of the American Society of Wood Engravers, its first secretary 1881–1882, and was vice-president of the Art Students' League 1882–1883.
He received honorable mention at the Paris Salon in 1881, and a second-class medal at an international exhibition of fine arts held in Munich in 1883.
Sylvester Koehler, in his paper on the United States contributed to the folio volume Die Radierung der Gegenwart ("Current engraving," Vienna, 1892–93), calls him the "boldest and most inconsiderate experimenter among the pioneers of the new school," but cites his reproduction of "Monticello" as a veritable triumph of wood engraving.
Juengling's reproductions of Kelly's illustrations in Scribner's Monthly (1877) is regarded by Weitenkampf as making "the first obvious, continued assertion of the new point of view."
