Mälk is an Estonian surname. Notable people with the surname include:
Mülk was a type of land tenure under the Ottoman empire.
Mülk was similar to freehold land; owners could buy, sell, and mortgage freely. It was exempt from some kinds of land taxes. Mülk was about more than just the land; it might also include the right to annual malikane payments from tenants and farmers.
In much of the near east, mülk can be contrasted against miri, which was effectively state-controlled land (perhaps a former mülk forfeited to the state when the owner had no heir to pass it on to).
In some ways, mülk was similar to vakuf property.
