Johann Baptist von Lampi the Younger (4 March 1775 – 17 February 1837) was an Austrian portrait painter.

He was born to the portrait painter, Johann Baptist von Lampi, now known as "The Elder", and his wife, Anna Maria née Franchi (1745-1795).

Upon completing his studies, in 1791, he accompanied his father and his younger brother, Franz Xaver (who was also a painter), to Saint Petersburg; enticed by an extremely generous offer from Catherine the Great.

He returned to Vienna with his wife and daughter in 1804, to accept a position at the court of Francis I, who had declared himself Emperor of Austria.
