2018–19 Davao Occidental Tigers season

The 2018–19 Davao Occidental Tigers season was the inaugural season of the franchise in the Maharlika Pilipinas Basketball League (MPBL).

The Tigers had a slow start, beginning the season 2–3, before winning 18 of the remaining 20 games, which included a 13-game winning streak. Finishing the season 20–5, Davao Occidental finished as the top seed in the South Division. In the playoffs, they first swept both Cebu City and Bacoor City before beating the defending champion Batangas City Athletics in a three-game South Division finals series to face the San Juan Knights in the national finals. Both teams alternated wins in the series, with the Tigers winning in game 4 to force a deciding game 5. Davao Occidental's championship hopes ended after a late push by San Juan took their lead, losing the series in five games.

Most of the team's home games were played at Rizal Memorial Colleges, though three games took place at the Davao City Recreation Center and one game at the University of Southeastern Philippines.
