Paulinenschlösschen, Cultural heritage villa in Bad Soden am Taunus, Germany.

Paulinenschlösschen is a three-story villa in Bad Soden am Taunus with outbuildings, a courtyard, and gardens within the Old Spa Park grounds. The complex also includes former stables and utility buildings that now serve different functions.

Duchess Pauline of Nassau first stayed in Bad Soden in April 1841, after her husband's death, and decided to build a summer residence there; the villa was completed in 1847. She sold it on 24 September 1855 to the balneologist Georg Thilenius, who ran a pension that hosted Princess Bismarck and her daughter in 1872. The town bought the property in 1909 and used it as its town hall until 1949.

The villa takes its name from Duchess Pauline, who used it as her summer residence. The place reflects how important spa stays were for wealthy people during the 1800s.

The building now houses the citizens' office and is not freely accessible for casual visits. Visitors should check in advance whether the villa is included in any guided tours or if viewing from outside is possible.

The opposite carriage house, or Remise, held Bad Soden's police and German Red Cross station until the 1970s; it now houses the ecumenical Diakoniestation. The complex also includes the Krug'sche Villa, built in 1845 as a summer residence for Frau von Krug of Darmstadt, bought by Georg Thilenius in 1861 and sold to the town in 1909; doctor's practices occupy it today.
