According to one embodiment, a magnetic resonance imaging apparatus includes an imaging unit and data processing condition setting unit. The imaging unit is configured to acquire magnetic resonance data corresponding to a sampling region asymmetric in a wave number direction in k-space from an object to generate image data based on the magnetic resonance data by data processing including phase correction and filter processing for obtaining a complex conjugate. The data processing condition setting unit is configured to set a condition for the data processing according to an imaging condition influencing a phase distribution used for the phase correction or the phase distribution.
