Which organic compound's NMR and IR are these? Can't find out. (Data available: Melting Point ~ 116 °C)
The integrals and shifts in the very simple NMR spectrum are a giveaway that this is a simple compound with two different types of aromatic signal, and another non-aromatic signal from a substituent, at a 2:1 peak integral ratio, hence possibly a para-disubstituted benzene ring with one proton in one substituent, none on the other. 

The IR spectrum is practically identical to that in the NIST webbook for p-nitrophenol.
Some other clues:


Oop Signal at $\pu{800 cm^-1}$: para substitution
$\pu{1400-1600cm^-1}$: aromatic cc stretch, matches nicely with typical appearance for para substitution
No peak at $\pu{1700cm^-1}$: no carbonyl
Weak signals at $\pu{3000cm^-1}$: sp2 stretch, no sp3
Signals at $\pu{1350 and 1500cm^-1}$ may be nitro


Note this is a little tricky - a search would show some variation in reported spectra.

The melting point also matches reported values. 

This is well in agreement with many of the comments under the original post.
