Geetu Mohandas () (1981) is a Malayalam film actress who started off as a child artist and did mainstream roles later.
Geetu's actual name is Gayathri Mohandas. Affectionately called Geetu by her family, the name was adopted as her screen name when she starred in her first movie Onnu Mudhal Poojyam Vare in 1986 with Mohanlal in the lead role. Geetu was five years old then and captured the hearts of Malayalam filmgoers as a fatherless child who discovers a father in an anonymous telephone caller. She acted in the top grosser En Bommukutty Ammavukku as the title role, which was the Tamil remake of Fazil's Ente Mamattikkuttiyammakku (Malayalam) done by Baby Shalini in the title role.
Geetu is now working on a film she plans to direct shortly.
