Pacific Express was an all-jet airline in the western United States from 1982 to early 1984,^{[3][4][5][6][7][8]} based in Chico, California.^[9][10] It later marketed itself as Pan Am Pacific Express^[11] reflecting a marketing agreement between Pan American World Airways (Pan Am) and the carrier for connecting passenger traffic at Los Angeles and San Francisco.^[12] At one point, Pacific Express served 22 destinations in the western United States.^[13] It was a subsidiary of WestAir Jet Inc.^[14]

Pacific Express initially operated seven British Aircraft Corporation BAC One-Eleven twin jets^[14] and subsequently then added Boeing 737-200s. It had six new British Aerospace BAe 146-200s on order^[14] but never took delivery; some of these BAe 146s were then purchased by Pacific Southwest Airlines (PSA).

Shortly after its second anniversary Pacific Express filed for bankruptcy in federal court and abruptly ceased operations on Thursday, February 2, 1984.^[4][6][7]

The name Pacific Express is now the callsign of Pacific Airlines, the second largest airline in Vietnam.
