The ClueFinders 3rd Grade Adventures: The Mystery of Mathra is a computer game in The Learning Company's ClueFinders series where the ClueFinders save the Numerian rainforest and Dr. Horace Pythagoras from a mysterious monster called Mathra. The game was re-released as "The ClueFinders: Mystery of the Monkey Kingdom" in 2001.

The game is the first in the series and depicts the first meeting of the ClueFinders and LapTrap[broken anchor], who goes on to appear in all the other ClueFinders games. The game ends with LapTrap being given to the ClueFinders and, in this respect, The Mystery of Mathra can be seen as an origin story for the rest of the series.
