Yes! Both of them are inelastic scattering of photons due to matter. However, there are certain marked differences! I'll list them below.

1) Raman Scattering occurs due to collision of a photon with a molecule thereby transferring energy to the molecule. But, in Compton Scattering, the photon is scattering by a free electron in a metal.

2) In Compton scattering, there is always a drop in frequency, i.e. the scattered photon has frequency less than incident photon.

In Raman Scattering, there are both frequencies higher and lower than that of the incident photons which leads to the so-called Anti-Stokes and Stokes lines in the scattered Spectra.

3) The scattering is independent of the nature of the material in Compton effect while Raman Scattering is dependent on the nature of material scatterer.

4) The wavelength shift in Compton effect is dependent on angle of scattering and is given by,

#Deltalamda = h/(m_0c)(1 - Cos theta)# where #m_0# is electronic mass.

However, scattering is independent of angle in Raman Effect.
