The Conservation and Art Materials Encyclopedia Online (CAMEO) is an electronic database that compiles, defines, and disseminates technical information on the distinct collection of terms, materials, and techniques used in the fields of art conservation and historic preservation.

It is developed and maintained by the Museum of Fine Arts, Boston, and used by conservators, historians, scientists, architects, journalists, and others worldwide as a reference.

CAMEO is available at cameo.mfa.org, and this logo/emblem is used on trade show banners and other printed collateral materials.
