Guido I. (franz: Gui de Montlhery, † 1095 ) was a Lord of Montlhery and Bray- sur -Seine from the house Montlhery. According to the Historia Francorum of Aimoin de Fleury, he was a son of Theobald of Montlhery.

• Elisabeth; ∞ with Joscelin of Courtenay - the parents of Count Joscelin I of Edessa
• Alix; ∞ with Hugo I of Le Puiset († 1094 ) ( House Le Puiset )

Longpont becoming the first branch of the Association clunizianischen monastery in the region around Paris. According to legend, his wife took with his own hands on the building.
