Prince Carl (Karl) of Solms-Braunfels (27 July 1812 – 13 November 1875) was a German prince and military officer in both the Austrian army and the cavalry of the Grand Duchy of Hesse. As commissioner general of the Adelsverein, he spearheaded the establishment of colonies of German immigrants in Texas. Prince Solms named New Braunfels, Texas, in honor of his homeland. Early years and family life Prince Friedrich Wilhelm Karl Ludwig Georg Alfred Alexander of Solms-Braunfels was born in Neustrelitz. His father was Prince Friedrick Wilhelm of Solms-Braunfels, second husband of Princess Frederica of Mecklenburg-Strelitz, who bore 13 children during the course of her three marriages.
