Eustace II, (d. 1093), count of Boulogne, was the husband of Goda, daughter of the English king Æthelred the Unready, and aunt of Edward the Confessor. He was the son of Eustace I.

Eustace paid a visit to England in 1051, and was honourably received at the Confessor's court. A brawl in which he and his servants became involved with the citizens of Dover led to a serious quarrel between the king and Earl Godwine.

The latter, to whose jurisdiction the men of Dover were subject, refused to punish them. His lack of respect to those in authority was made the excuse for outlawing himself and his family. In 1066 Eustace came to England with Duke William, and fought at the battle of Hastings.

In the following year, probably because he was dissatisfied with his share of the spoil, he assisted the Kentishmen in an attempt to seize Dover Castle. The conspiracy failed, and Eustace was sentenced to forfeit his English fiefs.

Subsequently he was reconciled to the Conqueror, who restored a portion of the confiscated lands.

Eustace died in 1093, and was succeeded by his son, Eustace III.
