The Antique Caterpillar Machinery Museum is a 501(c)3 non profit organization formed in 1996 by a group of Caterpillar enthusiasts from the Pacific Northwest. The objective of the Museum is to construct and operate a permanent museum dedicated to honoring the excellence and achievements of the Caterpillar product and its extensive contributions over many years of innovation and development.

The museum will engage an active program of exhibition, demonstration and education in a museum format. Aspects of the program will entail preservation and operation of antique Caterpillar equipment, collection and documentation of historical materials supported by development and operation of an archival library system, and pursuit of learning, education and enjoyment of the many facets of Caterpillar heritage.
