Abstract  The Hipparcos eclipsing binary V353 Hydrae has been observed visually in order to determine its period. Results of this campaign are presented. The system is an eclipsing binary in a circular orbit. The combination of visual, Hipparcos, and ASAS-3 data finally revealed that the period is 7.56 days.
