Henry de Beaumont, 1st Earl of Warwick (died 1119) was an English nobleman. He is also known as Henry de Neubourg.

Henry was the younger son of Roger de Beaumont and Adeline of Meulan. He inherited the modest lordship of La Neubourg, in central Normandy, but acquired a much greater holding in England, when, in reward for help in suppressing the Rebellion of 1088, William II of England made him Earl of Warwick.

Henry was one of those who immediately supported Henry I after the death of William II. He had been close to Henry II before the latter became king, and remained loyal (along with his brother) to the king when his rule was challenged by Robert Curthose.

Some time between 1106 and 1116 he was granted the lordship of Gower in Wales.

Henry was by disposition quiet and retiring, and was overshadowed by his elder brother Robert of Meulan, reputedly one of the most brilliant men in England.

He married Margaret, daughter of Geoffrey of Perche, and had, along with other children:

• Roger de Beaumont, 2nd Earl of Warwick, who succeeded him as earl;
• Robert de Neubourg, who inherited Henry's Norman lands, and was Chief Justiciar of Normandy;
• Rotrou, who was Bishop of Evreux and then Archbishop of Rouen, and who was Chief Justiciar and Steward of Normandy.
