Louis II (German: Ludwig II.; 15 August 1824 – 22 January 1858) was Grand Duke of Baden from 24 April 1852 to his death in 1858. He was the son of Leopold I, Grand Duke of Baden, and Princess Sophie of Sweden.

Louis was born on 15 August 1824 as a son of Leopold, Hereditary Prince of Baden (later Grand Duke Leopold I), and Princess Sophie of Sweden. The Grand Duke of Baden was his paternal uncle, Louis I, at the time of his birth. As the unbeknownst future heirs to the throne, Louis and his younger brother, Frederick, received a modern education and often travelled to northern Italy and the Netherlands on family trips during their childhoods.^[1] At the age of seven, Louis' father acceded to the throne of Baden.^[2] From December 1842 to May 1843, Louis and Frederick met high Austrian officials during a stay in Vienna. Louis later studied at the University of Heidelberg.

Louis succeeded his father as Grand Duke of Baden on 24 April 1852. His brother, Frederick, acted as regent, as Louis had mental illness. However, in 1856, Frederick became grand duke as well. He was also an honorary citizen of Karlsruhe. Louis died on 22 January 1858. Upon his death, he was succeeded by Frederick, who wrote that Louis had "a poor life full of misfortune and suffering".^[3]
