Konventum, is a conference centre associated with the Danish Confederation of Trade Unions (LO), located in Helsingør.

Konventum is built to a village-like design with many smaller buildings, alleys and "squares". Communal facilities are centred around the largest open space Atriumgården while residential quarters are located to the west, south and east. The architecture of the oldest part of the complex is inspired by traditional Japanese architecture while the buildings from the 1980s show inspiration from Arabian architecture.

The buildings are listed.
