The 1969 NBA World Championship Series to determine the champion of the 1968–69 NBA season was played between the Los Angeles Lakers and Boston Celtics. The Lakers were heavily favored due to the presence of three formidable stars: Elgin Baylor, Wilt Chamberlain, and Jerry West. In addition, Boston was an aging team; they made the playoffs as the fourth place team in the Eastern Division, and were not favored to make it to the finals. The Celtics' finals victory – the last championship of the Bill Russell dynasty – is considered one of the great upsets in NBA history.
