What was the name of the Apollo 17 lunar module?

The Apollo 17 lunar module was named Challenger.

Challenger carried astronauts Gene Cernan and Harrison Schmitt from lunar orbit to the Taurus–Littrow valley in December 1972. Ronald Evans remained in the command module, America, orbiting above the Moon while his crewmates conducted the final crewed lunar surface expedition of the Apollo program.

The name reflected the mission’s scientific and exploratory character. Apollo 17 was designed as a J-type mission, allowing a longer surface stay, more geological equipment, and extensive use of the Lunar Roving Vehicle. Cernan and Schmitt completed three moonwalks, collected samples, and investigated unusual orange soil near Shorty crater.

Challenger lifted off from the Moon on December 14, 1972, and reunited with America before the crew returned to Earth. The name is sometimes confused with Orion, Falcon, or Eagle, but those belonged to Apollo 16, Apollo 15, and Apollo 11 respectively. Apollo 17 remains the most recent mission to land humans on the Moon.
