The invention discloses a marine gravity data noise reduction method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring reference data and to-be-processed marine gravity data; taking the ocean gravity data as target gravity data; according to the reference data and the target gravity data, error evaluation processing based on the distance of the data points is carried out, and a root-mean-square result is obtained based on an error evaluation result; decomposing the target gravity data through two-dimensional empirical mode decomposition to obtain residual data and a plurality of modal data; traversing all modal data, respectively calculating correlation coefficients with the reference data, and determining target modal data based on the correlation coefficients; obtaining a local extreme value of the target modal data; performing Delauni triangulation based on the local extremum to obtain a plurality of initial triangles; performing noise reduction proc
