The Mogral River is a west-flowing river in the Kasaragod district in the Indian state of Kerala. It gets its name from Mogral, a coastal village on its northern banks. The river empties into the Arabian Sea in Mogral Puthur. It has a length of 34 kilometers and a drainage area of 132 square kilometers.
The river originates in Kanathur in the Karadka Reserve Forest, in Kasaragod. After flowing in a north-westerly direction through Bettipadi and Muliyar, it is joined by another stream rising from the northern part of Karadka Reserve Forest. From Yedhir, the river takes a meandering course and flows through the fairly flat regions of Madhur and Patla. Toward the end of its course, it forms a long stretch of backwaters several kilometers long.
