PICMG (PCI Industrial Computer Manufacturers Group) is a consortium of over 450 companies who collaboratively develop open specifications for high performance telecommunications and industrial computing applications. The members of the consortium have a long history of developing leading edge products for these industries. PICMG specifications include CompactPCI® for Eurocard, rackmount applications and PCI/ISA for passive backplane, standard format cards.

Founded in 1994, PICMG's original mission was to extend the PCI standard, as approved by the PCI Special Interest Group (PCI SIG), for computer systems such as PCI/ISA, PCI/EISA and the PCI/3U or 6U Eurocard form factor known as CompactPCI. PICMG continues to develop important extensions and improvements to CompactPCI. Recently, PICMG announced it was beginning development of a new series of specifications, called AdvancedTCA®, for next-generation telecommunications equipment, with a new form factor and based on switched fabric architectures.
