Gettu betur (English: Make a Better Guess) is an Icelandic team quiz show, broadcast on public television channel RÚV.

Each team consists of three students from one of Iceland's high schools or colleges.

The current host is Kristinn Óli S. Haraldsson.

A competitive trivia board game based on the show was introduced in 2001, containing over 2000 question cards.

The show has a prominent role in the plot of Arndís Þórarinsdóttir's 2011 novel Játningar mjólkurfernuskálds.
