Port Discovery Children's Museum is a non-profit institution located in the historic Fish Market building in Baltimore, Maryland's Inner Harbor.

The property and structure were donated to the City and the Museum operated out of this location for nearly 20 years.

A 35-million dollar capital campaign, led by the Board of Directors, resulted in the renovation of Downtown's historic Fish Market building, which became the new home to Port Discovery Children's Museum in December 1998.

[1] Port Discovery has served over 2.5 million visitors and ranks among the top Children's Museums in the U.S. by Parents Magazine[2](2015) and Forbes (2012).

In January 2011, Port Discovery was designated as a “Good to Grow Museum” for promoting healthy living for families.
