Showing Baltimore our gratitude through reliable access and innovative community programming.

Our Work

The National Aquarium's connection to Baltimore, to Maryland and to the entire Chesapeake region is not simply a matter of location; these are our communities. Our mission to inspire conservation of the world's aquatic treasures is deeply rooted here in Baltimore, and we carry this mission beyond our walls by providing accessible education experiences, innovative conservation initiatives and ample opportunity for reliable Aquarium access through an array of socially valuable programs.

Locals Visit for Less

Baltimore, this is YOUR Aquarium! We're proud to offer an ever-expanding lineup of opportunities for local residents to visit for free or reduced admission.

We encourage you to take advantage of the range of programs and events available to our surrounding communities. Please consult our calendar of events for specific dates and restrictions.

We're opening our doors and offering complimentary Aquarium access to the sea-star students, educators, caregivers and families who persevered and found scholarly success online, in the classroom—or both—during the ups and downs of the 2020-2021 academic year for one evening on June 17, 2021.

Our 2021 School Shell-ebration has sold out! Please register here for information on future events.

Nonprofit Partnership

As a nonprofit organization whose mission is to inspire conservation of the world’s aquatic treasures, the National Aquarium is eager to support other organizations in achieving their missions as well. We believe that, working together in our roles as vital community resources, nonprofit organizations strengthen our neighborhoods and ensure that all Marylanders can enjoy access to a vibrant array of accessible educational and recreational opportunities. When we work together, we help our communities to fully participate in and benefit from everything our city, state and region have to offer while building stronger, more resilient communities.

The Aquarium receives hundreds of ticket donation requests each year from other community nonprofits for charitable or fundraising purposes. Thanks to the generosity of friends, corporate partners and foundations, we are able to help our fellow nonprofits by granting as many requests as we possibly can each year.

Please note: All ticket donation requests must be made via our online form at least two months in advance of your event for consideration.

Donation Criteria and Guidelines

  • The Aquarium will consider ticket donation requests from other 501(c)(3) organization serving Maryland communities. Preference is given to those that have conservation-focused missions or activities, promote successful outcomes for youth or families and help build strong communities.
  • We cannot grant requests involving animal interactions, memberships or behind-the-scenes tours.
  • All donation requests must be received a minimum of two-months prior to the date of the event. If your organization misses this deadline, feel free to submit your request for the next year.
  • While you are free to submit multiple requests for different events, the Aquarium will only fulfill one request per organization per year.

Thanks to the generous support of our corporate community, the Aquarium is able to provide complimentary Community Connections tickets to qualifying nonprofits organizations, allowing their members to experience the Aquarium as guests of our corporate family.

Please note: While all applications are thoughtfully reviewed and considered, applications from civic organizations or social clubs are generally not accepted.

Donation Criteria and Guidelines

  • The Aquarium's Community Connections program will consider requests from Maryland-based nonprofits with 501(c)(3) status. We require inclusion of tax-exempt documentation upon submission of your application for verification purposes.
  • Qualifying nonprofits must agree to assign a day-to-day administrator of ticket distribution or group booking.
  • Qualifying nonprofits must agree to complete an annual evaluation to review ticket program effectiveness and use.
  • Requests are accepted on a rolling basis. Please allow four-to-six weeks for review and response.
  • Requests may be made for individual tickets to distribute to your organization's constituents as you deem appropriate, or for group visits.
  • Once accepted, your application does not need to be resubmitted, but additional future ticket requests will be reviewed against new applications.

Thanks in part to Maryland State Department of Education grant funding, the National Aquarium is able to serve more than 100,000 schoolchildren annually. We offer free visits for all Maryland school groups, in addition to a variety of other free or discounted school programs. Therefore, requests for donations to schools are generally declined.
