"Party President Akhilesh Yadav has dissolved the state executive. All district executives, executives of youth and other wings have also been dissolved," said a source.
State President Naresh Uttam, however, will continue to discharge his duties.
Yadav had, earlier, dissolved the media panel for the party and had stopped party spokespersons from participating in TV debates.
According to sources, he is planning a massive revamp within the party and will constitute the organisation afresh.
The Samajwadi Party, once a vibrant political organisation, has turned into a political nonentity after the defeat in the Lok Sabha elections which left the party with merely five seats.
The snapping of the alliance with the Bahujan Samaj Party further demoralized the party cadres.
