The civil cases, in which three men accused Spacey of sexual assault between 2000 and 2013, were due to go to trial in London's High Court later this year.
No details of the settlement are known.
Spacey was acquitted in 2023 of a series of sexual assault charges against four men. Several charges have also been brought against him in the United States, but all have been dropped.
The allegations against the two-time Oscar winner Spacey began to emerge in connection with the #MeToo movement in 2017. They led to his firing from the Netflix series "House of Cards." He has denied all the allegations and has not been convicted in any case.
