how about methane?
(yeah Helium gas wins out over Methane - electronegativity difference of 0, very low solubility in water)
Monoatomic helium is not a molecule, it is a free radical

It's a bit difficult to judge this as there's not really a set scale for this kinda thing. Plus your question is somewhat contradictory.
Most organic molcules will be hydrophobic (water-repellant) to some degree, but then 'non-polar' is a completely different specification, requiring electronic charges to be equally balanced across the entirety of a molecule.
While the above poster is correct in saying that CH4 is non-polar, there is almost no difference in polarity beween that and something like CCl4 or CI4. And I couldn't tell you the difference in how hydrophobic they are without consulting numerous tables and charts, which I don't have to hand.

Monatomic helium would win hands down.
