Frederik Ferdinand "Fred" Ormskerk (26 April 1923 – 1 May 1980) was a Surinamese military leader.

After a KNIL training at Camp Casino, Australia, he arrived in Batavia (now Jakarta).

There, he became a soldier in the newly formed Korps Speciale Troepen (KST), led by Captain Westerling.

Ormskerk allegedly launched a failed counter-coup on April 30 and afterwards was arrested, tortured and killed.
