The USS Magnan (NCC-13843) was a Mission-class Federation starship in service in the 23rd century.

In 2270, the Magnan was assigned to ferry Federation ambassador Carlos Rivera to the Lorealyn system within the Klingon Neutral Zone to negotiate possible membership into the United Federation of Planets. (FASA RPG module: Star Trek IV Sourcebook Update)

The Magnan was likely named for the minister of war who served under French emperor Napoleon III.
