Friedrich Wilhelm L'Allemand, known as Fritz (24 May 1812, Hanau - 20 September 1866, Vienna) was an Austrian history painter.
His eldest brother, Conrad [de] worked as a medallist in Frankfurt am Main and Hannover.
From 1827, he studied at the Academy of Fine Arts with Josef Klieber and Joseph von Führich.
He received support from the history painter, Johann Peter Krafft, who was also originally from Hanau.
At first, he focused on portraits and genre scenes, but later turned to painting battles; some generic, some historic.
