The United Nations Development Programme (UNDP) Multi-Donor Trust Fund Office (MDTF Office), established in 2006, was built on the experience of the United Nations Development Group Iraq Trust Fund (UNDG ITF) and other Multi-Donor Trust Funds (MDTFs) administered by UNDP.

When donor funds are intended for multi-agency operations, the MDTF Office may be appointed as the fund administrator for the UN system. The MDTF Office provides a one-stop shop with focused support and service to UN Country Teams (UNCTs), national governments and donors. It enhances the UN’s accountability for its growing role in MDTFs that use the pass-through fund-management modality established in the context of humanitarian, transition, reconstruction and development programmes.

This currently has a portfolio of more than 45 distinct MDTFs and over 25 Joint Programmes (JPs). The increasing use of JPs and MDTFs is a direct application of the Aid Effectiveness Agenda and UN Reform initiatives and responds to the need to provide flexible, coordinated and predictable funding to support the achievement of national priorities.

The mission of the office is "To provide transparent and accountable fund management services to the United Nations system to enhance its coherence, effectiveness and efficiency.
