The Portrait of a Young Man with a Lamp is an oil-on-canvas painting by the Italian High Renaissance painter Lorenzo Lotto, dating to c. 1506.

The use of light and the composition are similar to other early works by Lotto, such as the Portrait of Bishop Bernardo de' Rossi (1505).

The face is framed by the dark clothes and hat, painted over a white brocade drapery with a green border.

On the right, an opening to a darker background shows a burning lamp, a symbol which could allude to the man's personality or deeds, and which has been variously interpreted (from a reference to an evangelic episode to an allegory of the human life's shortness, due to the dimness of the flame).

The subject has been identified as Broccardo Malchiostro, the young chancellor of the bishop of Treviso, Bernardo de' Rossi, who both risked their lives in a plot in 1503.
