District Grants are small grants, management by the District, using funds from The Rotary Foundation.  Your club may apply for one of these grants (which usually involve a grant award of $1000 to $4500) to do a humanitarian project either in your home community or perhaps in a community across the globe. In so doing, you will be making a difference to people in need and taking advantage of the matching opportunities of The Rotary Foundation.
The project described in your Grant application must align with one of Rotary's Areas of Focus, and it must be new to the club.  Other criteria, as well as the application, are set forth in these pages.  Remember, these grants are competitive:  Your Club MUST apply for the grant by June 1, and  your club MUST be "qualified" in order to apply. So check out the "Club Qualifications" and Criteria described here.
