The Dunedin History Museum is a local history museum located in downtown Dunedin in the U.S. state of Florida. Founded in 1970, the museum is housed in a former railroad depot built by the Atlantic Coast Line Railroad in 1924. The former rail line that serviced the depot, originally built by the Orange Belt Railway in 1888 and last used for a series of special excursion trips from nearby Tarpon Springs and back on March 8, 1987, was converted into a section of the Pinellas Trail in the 1990s. The museum contains more than 2,000 artifacts, 2,500 photographs, and a library of books that convey a great deal of information on Dunedin's past. The museum provides special programming for schools and summer camps as well as a rotating special exhibit gallery.
