Jacob Hansens hus, 17th-century timber-framed merchant house in Helsingborg, Sweden

Jacob Hansens hus is a two-story timber-framed building with red-painted brick infill between dark beams. The upper floor projects over carved brackets, and the steep gable roof is covered in reddish-brown clay tiles. Two arched doorways open onto Norra Storgatan, and the main door has a Latin inscription dated 1641.

Jacob Hansen, a merchant and town councillor, built the house in 1641 with his wife Inger Mogensdotter; it was the main building of a farm covering the whole Sockerbruket block. The farm was slightly damaged in the Horn War (1644–1646) but repaired. After Hansen died in 1652 and his wife in 1660, their son-in-law Svend Pihl took over. In 1680 Ulrika Eleonora, Karl XI's future queen, stayed here on her journey from Denmark. The house survived the Danish army's 1679 destruction of Helsingborg's fortifications.

The Latin inscription above the main door reads "O DOMINE BENEDIC DOMVM ISTA ET OMNES HABITATES EAIACOB HANSEN INGER MOGENSD ANNO 1641", asking God to bless the house and all who live in it. It names the merchant Jacob Hansen and his wife Inger Mogensdatter. In the Blue Hall and Red Room, ceiling paintings by Hugo Gehlin depict Helsingborg's history and the house's owners.

The house stands on Norra Storgatan beside Tycho Braheplatsen, and its two vaulted portals open onto that street. The interior, including the Blue Hall and Red Room with Hugo Gehlin's ceiling paintings, is used for festivities and conferences, so entry follows the bookings of those events rather than fixed visiting hours.

The Latin inscription over the main door names Jacob Hansen and Inger Mogensdatter with the year 1641 and asks God to bless the house and all who live in it. The upper floor held three large halls, and the northern ground-floor room served briefly as a pharmacy after 1683.
