What is the name of the protagonist in 'The Picture of Dorian Gray'?

The protagonist in 'The Picture of Dorian Gray' is Dorian Gray.

Dorian is a beautiful young man whose portrait is painted by the artist Basil Hallward. After hearing Lord Henry Wotton praise youth and sensual pleasure, Dorian wishes that the portrait would grow old instead of him. The supernatural wish is granted: Dorian remains outwardly youthful, while the painting records the moral damage caused by his choices.

Oscar Wilde uses Dorian's transformation to explore beauty, influence, temptation, morality, and the relationship between art and life. Basil, Lord Henry, and Dorian form the novel's central triangle, but Dorian remains the character whose decisions drive the plot.

James Vane is Sibyl Vane's protective brother, Basil Hallward is the painter, and Lord Henry Wotton is the aristocrat whose philosophy influences Dorian. None of these characters is the protagonist. The novel first appeared in 1890 and was expanded into book form in 1891.
