Police are searching for the mother of a newborn baby found abandoned on a doorstep in south-west New South Wales.

Residents answered their doorbell on Sunday night to find the baby boy on their doorstep wrapped in a pink cloth bassinet, according to police.

The baby, believed to have been born on Friday morning, was taken to Griffith Base Hospital after the residents called triple zero.
