The Wall was the third season of the Greek reality television series Big Brother.

The show followed eighteen contestants, known as housemates, who were isolated from the outside world for an extended period of time in a custom-built house.

In 2003, Big Brother Greece 3 launched under the name The Wall on ANT1 on March 10 and ended on June 30, last 113 days.

The last remaining housemate, Thodores Jspógloy, was declared the winner, winning a cash prize of €300,000.

Expectations for the format proved unsuccessful with ANT1 choosing not to use it again.
