The 1979 Copa Polla Gol was the ninth edition of the Chilean Cup tournament. The competition started on February 17, 1979, and concluded on April 14, 1979. Only first level teams took part in the tournament. Universidad de Chile won the competition for their first time, beating Colo-Colo 2–1 in the final. The points system in the first round awarded 2 points for a win, increased to 3 points if the team scored 4 or more goals.

The team with the most points after the two legs advanced to the next round. If both teams were equal on points, an extra time took place (goal difference and away goals did not count).
