The Starfleet Corps of Engineers (also known as Starfleet Engineering or Starfleet Engineering Corps) is a Starfleet division that deals with specialized engineering problems.

The Corps of Engineers was responsible for the construction of the underground laboratory complex on the Regula asteroid, where the second phase of the Genesis Project was conducted. (Star Trek II: The Wrath of Khan).

In an alternate reality experienced by Harry Kim in 2372, he worked at the Starfleet Engineering Corps. (VOY: "Non Sequitur")

In 2375, during the Dominion War, Klingon starships could be made immune to the Breen energy dampening weapon by adjusting the tritium intermix of their ships' warp cores. This "fix" would not work on Federation ships and Starfleet Chief Miles O'Brien forwarded his findings to Starfleet Engineering for more in-depth analyses. (DS9: "When It Rains...")

In 2377, Captain Kathryn Janeway lamented that they didn't have a Corps of Engineers to build a planet-wide system of atmospheric processors to decontaminate Brin's homeworld. (VOY: "Friendship One")

The Corps are named and based after the United States Army Corps of Engineers
