The Welsh Socialist Republican Movement (Mudiad Sosialaidd Gweriniaethol Cymru) was a short-lived nationalist political movement which was born out of frustration with Plaid Cymru's failure to oppose the first referendum on Welsh Devolution in 1979 in order to map out a specific policy of arguing for Independence. It was also an attempt to develop a Welsh Socialist alternative to Plaid Cymru and it produced pamphlets and a newspaper called Y Faner Goch (The Red Flag).
