Louis Ferdinand, Prince of Prussia (German: Louis Ferdinand Victor Eduard Adalbert Michael Hubertus Prinz von Preußen; 9 November 1907 – 26 September 1994) was a member of the princely House of Hohenzollern, which occupied the Prussian and German thrones until the abolition of those monarchies in 1918.

When Louis Ferdinand's older brother Prince Wilhelm renounced his succession rights to marry a member of the untitled nobility in 1933 (he was later to be killed in action in France in 1940 while fighting in the German army), Louis Ferdinand replaced him as second in the line of succession to the defunct German and Prussian thrones after the former Crown Prince.

In 1968 Der Spiegel reported that in a survey of their readers by Quick magazine about who would be the most honorable person to become President of the Federal Republic of Germany, Louis Ferdinand, the only one of twelve candidates who was not a politician, won with 39.8% before Carlo Schmid and Ludwig Erhard.

Instead of complying with his last wish after his death, the king had been laid to rest in the Garrison Church (Potsdam) next to his unloved father Frederick William I of Prussia in 1786.

Sulzberger for the book The Fall of Eagles, Louis Ferdinand expressed a deep sense of admiration for the informal bicycle monarchy and crowned republic style favored and used by the Dutch, Belgian, and Scandinavian royal families.

Praising how vehicles carrying the King or Queen would stop and wait at traffic lights, Louis Ferdinand stated that if the House of Hohenzollern were ever restored to the German throne during his lifetime, this same informality was a quality he fully intended to emulate.
