Almarestäket, or ''Stäket'', is a strait at the inlet of Lake Mälaren in mid-east Sweden. A fortress existed there between about 1370 and 1517, also named Almarestäket.

There was a fortress built here in the mid-late 14th century, under the reign of Albert of Sweden. It was located on the small island ''Stäkesön'' in the middle of the strait.

As a revenge for this and other perceived injustices, Trolle, assisted by the Danish King Christian II, took revenge in the Stockholm Bloodbath of 1520.
