Heinrich Ludwig Ferdinand von Arnim (15 September 1814 – 23 March 1866) was a German architect and watercolour-painter.

He trained as a land surveyor and studied architecture at the Royal Prussian Building School (Bauakademie) in Berlin between 1833 and 1838.

Having completed his studies, he joined the Berlin Architects' Association in 1839, from 1840 he worked as site foreman under Friedrich Ludwig Persius and in 1844 was appointed building inspector official.

Upon Persius' death in 1845, Arnim became a member of the Berlin City Palace building committee under Friedrich August Stüler and house architect of the Hohenzollern prince Charles of Prussia at his residence in Klein-Glienicke.

He was entombed in the part of the Potsdam-Bornstedt cemetery (near the tomb of his mentor Ludwig Persius); nearby were buried the famous Sello family of court gardeners.
