The Serbian eased to a 6-3 6-3 victory, which brings him level at 23-23 in career meetings with the Spaniard.
Djokovic has now won eight of his last nine matches against Nadal.
Djokovic was beaten by Roger Federer in the group stages of the season-ending tournament, disputed on a hard court between the year's top eight players at London's O2 Arena.
Spanish fifth seed Nadal won all three of his group matches to reach the semi-finals but there was little he could do to stop the defending champion in this sort of form.
If the Serb lifts the trophy for a fifth time, he will become the first player to win the Tour Finals four years in a row.
