The Boeing 737-600 is a short-to-medium-range, narrow-body airliner and the smallest member of the 737 Next Generation (NG) family, which also includes the 737-700, -800, and -900. Introduced in the late 1990s as a replacement for the aging 737-500, the -600 brought improvements in avionics, fuel efficiency, and range, but it struggled commercially due to its limited capacity compared to larger NG siblings.

The aircraft was certified in 1998, with SAS (Scandinavian Airlines) as its launch customer. Production ended in 2006 after just 69 units were built, making it the least-produced 737 NG variant.
