| ConFiction, the 48th World Science Fiction Convention | |
| Dates: | 23–27 August 1990 |
| Attendance: | 3,580 |
The 48th World Science Fiction Convention (Worldcon), also known as ConFiction, was held 23–27 August 1990 at the Netherlands Congress Centre in The Hague, Netherlands.
The organising committee was chaired by Kees van Toorn.
Attendance was 3,580, despite the preparations for the Gulf War which deterred many Americans from traveling.
The convention was opened by the then Minister of Cultural Affairs of the Netherlands, and the Hugos were presented by the U.S. Ambassador to the Netherlands.
This was the first Worldcon after the fall of the Berlin Wall, so was the first convention which many fans, writers and editors from Eastern European countries were able to attend.
