Antvorskov County (Danish: Antvorskov Amt) was a county on the southwestern part of Zealand, Denmark.
Antvorskov County was created in 1662 as a replacement of the old Antvorskov Fief (Antvorskov Len). The county consisted of two hundreds, Vester Flakkebjerg Herred and Øster Flakkebjerg Herred. At the 1793 Danish County Reform, with effect from 1798, Antvorskov County, Ringsted County and Korsør County were merged into Sorø County.
