Hans Sandreuter (11 May 1850, Basel - 1 June 1901, Riehen) was a Swiss artist and designer who painted in the Symbolist style.
He then worked for a short time in Nuremberg before heading to Verona for further studies with Achille Carrillo; returning to Basel in 1872.
Through his intercession with Wilhelm von Kaulbach, Sandreuter was able to attend the nude drawing classes at the Academy of Fine Arts.
He received numerous contracts for murals in public buildings; notably the monastery in Stein am Rhein.
The following year, he returned briefly to Florence, where he worked on preparing the Böcklin Exhibition for the Kunsthalle Basel.
