The Garden Theater Block is a historic commercial block and theater at 353-367 Main Street in Greenfield, Massachusetts. The Colonial Revival block was built in 1928, and movies were first shown in the theater in 1929. The theater had, at its greatest extent, a seating capacity of over 1,800, and was richly decorated with garden-themed carpeting and murals of New England scenes by noted theater muralist Frederick Marshall. It also featured a marquee with Tiffany-inspired design, but as the building deteriorated it was removed and placed in storage. The block was listed on the National Register of Historic Places in 1983, and included in the Main Street Historic District in 1988.
