Support Your Local Chamber of Commerce Day is Oct. 21

Every October, communities take a day to recognize the important work chambers of commerce do to strengthen local economies, support small businesses and create opportunities for growth. This year, Support Your Local Chamber of Commerce Day is Wednesday, Oct. 21, 2026. It is the perfect opportunity to highlight the positive impact chambers make.

ACCE’s Support Your Local Chamber Day resource page, provided in partnership with Comcast Business, offers tools and ideas to help you spread the word, including ready-made social media graphics, sample posts, tips for engaging your members and guidance on generating local media attention.

Chambers of commerce are more than membership organizations. They champion businesses of all sizes, convene community leaders and advocate for policies that drive prosperity. Support Your Local Chamber of Commerce Day is a reminder to:

• Celebrate your chamber’s contributions to your community.
• Recognize the members and volunteers who make the work possible.
• Share stories that highlight the chamber’s role in building a strong local economy.

Engage Your Members

Support Your Local Chamber of Commerce Day is also an opportunity to amplify your members' voices. Encourage businesses to share their “why”: why they support the chamber, why membership matters to them and what they gain from being part of your network.

When members tell their own stories, it shows the real impact of chamber involvement. A testimonial from a small business owner, a story of collaboration between members or a reflection on the chamber’s role in their success can be more powerful than any marketing message. These authentic stories help others see the value of chamber support and inspire new connections.

How To Get Involved

• Share on social media: Download graphics and sample posts from our resource page.
• Highlight your members: Encourage members to share their own stories about the value of chamber membership on their channels and amplify their message to your own.
• Host an event or open house: Use the day to bring people together and showcase your chamber’s work.
• Engage community leaders: Submit a request from local government for a proclamation or to share messages of support.
• Tag @ACCEHQ for a chance to have your content shared and use #SupportYourLocalChamberofCommerce and #ChambersChangeThings.
