Portrait of Giovanni di Nicolao Arnolfini is a small c. 1438 portrait by Jan van Eyck believed to be the same person as in the famous 1434 Arnolfini Portrait due to the similarities of facial features. Thus, the work is van Eyck's second portrait of Giovanni di Nicolao Arnolfini, a wealthy merchant from Lucca, a city in Tuscany in central Italy, who spent most of his life in Flanders. The painting was long thought a self-portrait; in colourisation, costume and tone, it is very similar to the signed and dated Portrait of a Man in a Red Chaperon in London, which is generally accepted as a self-portrait. It was only later that the current work was associated with Arnolfini and the double marriage painting. It is today in the Gemäldegalerie, Berlin.
