Techniques for filter sharing are described. An apparatus may comprise a shared filter manager component for an application program. The shared filter manager component may be operative to manage shared filtering operations for the application program. The shared filter manager component may comprise a shared filter interface module operative to receive a selection for a shared filter component to filter multiple source data objects, and assign the shared filter component to the multiple source data objects. The shared filter manager component may further comprise a shared filter control module communicatively coupled to the shared filter interface module. The shared filter control module may be operative to filter data from the multiple source data objects using the shared filter component. Other embodiments are described and claimed.
