Harald Riipalu (born as Harald Reibach) (13 February 1912 – 4 April 1961) was an Estonian commander in the German Wehrmacht and the Waffen-SS during World War II.

After the Soviet occupation of Estonia in 1940, Riipalu was forcibly mobilized into the Soviet Army 22nd Territorial Corps, serving until 1941, at which time he defected to the German side.

On 23 August 1944 he was decorated with the Knight's Cross of the Iron Cross for his actions in the Battle of Tannenberg Line and in the Battle of Auvere where Riipalu and his regiment drove back the assault of the Soviet Army, which prevented the encirclement of Army Detachment Narwa.

The award was presented to him by Felix Steiner, the commander of III SS Panzer Corps.

After the end of the war, Riipalu evaded Soviet captivity by fleeing to Denmark.
