7 Powerful Sample Letter of Support Templates for Grant Applications
Why These Templates Will Help Secure Your Grant Funding
Letters of support can make or break your grant application. According to a survey of foundation program officers, applications with strong, specific letters of support are 35% more likely to receive funding than those without such endorsements. However, many organizations struggle to create compelling support letters that truly strengthen their case.
This comprehensive collection of letter of support templates for grant applications has been specifically designed to address the most common scenarios nonprofits encounter when seeking funding. Each template follows proven frameworks that grant reviewers respond to positively, helping your application stand out in a competitive funding environment.
Whether you're a community partner, technical expert, government agency, or program beneficiary, these templates will help you craft professional, persuasive letters that demonstrate genuine commitment and maximize the applicant's chances of securing funding.
How to Use These Templates Effectively
These templates are starting points that should be thoroughly customized to reflect your unique relationship with the applicant organization and specific contributions to the project. Generic, template-like letters can actually harm an application rather than help it.
For each template:
Replace all bracketed text with your specific information
Add details that demonstrate genuine knowledge of the project
Include concrete, specific commitments whenever possible
Mention relevant data or experiences that validate the need
Tailor language to align with the specific grant program's priorities
Use your organization's letterhead and professional formatting
Remember that the most effective letters of support for grants are concise (1-2 pages), specific about your contributions, and clearly explain why you believe the project will succeed.

RE: Letter of Support for Neighborhood Nutrition Network's Healthy Food Access Project
Dear Ms. Grant:
I am writing to express Community Health Partners' enthusiastic support for Neighborhood Nutrition Network's (NNN) application to The Wellness Foundation's Community Health Initiative for their Healthy Food Access Project.
As the Executive Director of Community Health Partners (CHP), I have collaborated with NNN for the past five years on various health equity initiatives in our shared service area. Our organization provides primary healthcare services to over 3,500 low-income residents annually in the same neighborhoods that NNN's project will serve. Through this close working relationship, I have consistently observed NNN's deep community connections, cultural competence, and commitment to evidence-based approaches.
The proposed Healthy Food Access Project addresses a critical need in our community. According to our organization's 2024 Community Health Assessment, 42% of residents in the targeted neighborhoods live in USDA-designated food deserts, with the nearest grocery store being more than 1.5 miles away. This project's innovative approach of combining mobile produce markets, nutrition education, and micro-enterprise development for local food entrepreneurs represents a comprehensive solution that addresses both immediate food access needs and long-term system change.
Community Health Partners is committed to supporting this project through:
• Integration of project referrals into our patient care protocols, with an estimated 500 patient referrals annually
• Provision of space at our main clinic location for weekly nutrition education classes
• Contribution of our Registered Dietitian's time (4 hours monthly) for program planning and evaluation
• Sharing of relevant health outcome data (with appropriate privacy protections) to support project evaluation
The anticipated outcomes of this project align perfectly with The Wellness Foundation's priorities, particularly your focus on addressing social determinants of health and building community capacity. Based on NNN's successful implementation of their previous Cooking Matters program, which achieved a 78% completion rate and demonstrated significant improvements in participants' nutritional knowledge and behaviors, I am confident they will successfully implement this expanded initiative.
What particularly distinguishes NNN's approach is their authentic community engagement model. Their staff and board reflect the diversity of the neighborhoods they serve, and all programming is developed with substantial input from community members. This approach ensures cultural relevance and fosters the community ownership necessary for sustainable impact.
Please feel free to contact me at (555) 123-4567 or director@chpartners.org if you require any additional information regarding our support for this valuable initiative.
Sincerely,
