Monochamus is a genus of longhorn beetles found throughout the world. They are commonly known as sawyer beetles or sawyers, as their larvae bore into dead or dying trees, especially conifers[1] such as pines. A more ambiguous name is "bark beetles". They are the type genus of the Monochamini, a tribe in the huge long-horned beetle subfamily Lamiinae, but typically included in the Lamiini today.

While sawyer beetles are economically insignificant by themselves, some species are known to transport phoretic Bursaphelenchus nematodes, including B. xylophilus which causes pine wilt disease.[2]
