Johan Gustaf Ruckman (December 12, 1780 – January 20, 1862) was a Swedish engraver.
[1] In 1805, being a pupil of Johan Wilhelm Palmstruch, Ruckman helped with the preparation of tables in Palmstruch's work Svensk botanik ("Swedish Botany").
Ruckman found time to further develop his artistry and designed a number of portraits.
He also illustrated fashion journals, calendars, and children's books; writings of the Swedish Academy of Sciences and other scientific institutions; and about 100 map sheets.
Ruckman is well represented in the collection of engravings of the Swedish National Museum.
