Sæbyholm was a manor house located close to Nakskov on the island of Lolland in southeastern Denmark.

The estate was acquired by Christian Heinrich August Hardenberg-Reventlow of Krenkerup in 1801 and has been owned by his descendants since then.

[1] After Lene Rud's death in1671, her heirs sold the estate to Helmuth Otto von Winterfeldt.

Christian Heinrich August Hardenberg-Reventlow managed Sæbyholm as a farm under Krenkerup, the centre of the countship he had created in 1815.

Henrik Ludwig Erdmann Georg Haugwitz-Hardenberg-Reventlow parted with 230 hectares of land from the Sæbyholms estate in connection with the transaction.
