The Bede BD-5 Micro is a series of small, single-seat homebuilt aircraft created in the late 1960s by US aircraft designer Jim Bede and introduced to the market primarily in kit form by the now-defunct Bede Aircraft Corporation in the early 1970s. In total, only a few hundred BD-5 kits were completed, although many of these are still airworthy today. The BD-5J version holds the record for the world's smallest jet aircraft, weighing only 358.8 lb (162.7 kg).
