Jacob's Well (Arabic: بئر يعقوب‎, Bir Ya'qub, Hebrew: באר יעקב‎; also known as Jacob's fountain and Well of Sychar) is a deep well hewn of solid rock that has been associated in religious tradition with Jacob for roughly two millennia. It is situated a short distance from the archaeological site of Tell Balata, which is thought to be the site of biblical Shechem.

We follow the lower road, and 1 1/4 h. from Hawaira brings us to Jacob's Well, just at the entrance of the valley that leads up to Nâbulus. Here the Saviour rested at noon-day, wearied with the long walk up the hot plain, having come like ourselves from Jerusalem. There is little to be seen at it; and the traveller may either satisfy his curiosity by a passing look now, or, as I would recommend, he may return in the still evening or the quiet morning to read the story of that strange interview between our Lord and the Samaritan woman, and to allow the mind to luxuriate in those holy associations which the spot calls up. An account of the well and its history I give below. The little white enclosure a few hundred yards to the N. is Joseph’s Tomb. (See below.) 1/2 h.’s ride up the glen brings us to Nâbulus.
