The present invention relates to a query definition apparatus and method for multi-tenant. The query definition apparatus includes a schema generation unit for, when a tenant accesses a Software as a Service (SaaS) system, generating a basic schema required to execute an application program requested by the tenant on a SaaS platform. A schema editing unit edits the basic schema in response to a request of a tenant manager. A query definition unit is configured to, when the basic schema is edited, provide a query definition interface required to define queries for the edited schema to the tenant manager, and define a query statement by extracting corresponding queries depending on manipulation of the query definition interface.
