A process for producing cyclic olefins by catalytic hydration of cyclic olefins is disclosed, wherein the hydration is conducted in the presence of a crystalline aluminosilicate containing at least one member selected from the group consisting of titanium, zirconium, hafnium, chromium, molybdenum, tungsten, and thorium. The hydration reaction achieves high conversions and selectivities, and the catalytic activity is retained for a long time.
