Mararikulam Assembly constituency was one of the 140 state legislative assembly constituencies in Kerala state in southern India, that existed before the 2008 delimitation of constituencies. It was also one among the seven state legislative assembly constituencies included in the Alleppey Lok Sabha constituency.
The Mararikulam constituency came into existence in 1957. It was represented by veteran Communist leader and former Chief Minister VS Achuthanandan from 1991 to 1996. In 1996, Achuthanandan suffered a shock defeat from a constituency that was otherwise considered to be a communist bastion. This thwarted Achuthanandan from becoming the Chief Minister. He had to wait for another decade, until 2006, when he could fulfill his ambition, this time being elected from the Malampuzha constituency.
The following list contains all the members who have represented the constituency in the Kerala legislative assembly.
