Henry II (1206 – 1229), was the margrave of Namur from 1226 to his death.
He was the third son of the Peter II of Courtenay, Latin Emperor and Yolanda of Flanders. When his eldest brother, Philip II, Marquis of Namur died in 1226 without an heir, his second brother Robert was already Latin Emperor in Constantinople, so Henry became the new Margrave of Namur, under regency of Enguerrand III, Lord of Coucy.
When his brother Robert died in 1228, Henry renounced the title of Latin Emperor, which went to his younger brother Baldwin.
Henry died himself one year later without children, and he was succeeded by his sister Margaret, married to Henry, count of Vianden.
