  We present the results of long-term spectropolarimetric and spectroscopic
monitoring of MWC 314, a candidate Luminous Blue Variable star. We detect the
first evidence of H$\alpha$ variability in MWC 314, and find no apparent
periodicity in this emission. The total R-band polarization is observed to vary
between 2.21% and 3.00% at a position angle consistently around
$\sim0^{\circ}$, indicating the presence of a time-variable intrinsic
polarization component, hence an asymmetrical circumstellar envelope. We find
suggestive evidence that MWC 314's intrinsic polarization exhibits a
wavelength-independent magnitude varying between 0.09% and 0.58% at a
wavelength-independent position angle covering all four quadrants of the Stokes
Q-U plane. Electron scattering off of density clumps in MWC 314's wind is
considered as the probable mechanism responsible for these variations.
