Aleksander (Alexander) Laak (24 August 1907 – 6 September 1960) was a lieutenant and the commander of the Jägala concentration camp during the German occupation of Estonia. The estimates for the number of killed at Jägala concentration camp vary widely. The Soviet investigators reached the conclusion that 2,000–3,000 were killed in Jägala and Kalevi-Liiva taken together, but the number 5,000 (as determined by the Extraordinary State Commission in 1944) was written into the verdict. Aleksander Laak was also known to have arranged drunken orgies with inmates.
