2019–20 Pasig Sta. Lucia Realtors season

The '''2019–20 Pasig Sta. Lucia Realtors season''' was the second season of the franchise in the Maharlika Pilipinas Basketball League (MPBL).

The team, now backed by Sta. Lucia Land, looked to improve from a dismal 4–21 campaign, which saw Pasig claim the worst record of the season. They would surpass that in win percentage with their fifth victory on August 2. The Realtors got off to a 9–3 start before finishing the season 18–12, ranked seventh in the North Division. They would be swept by the Manila Stars in the Division Quarterfinals.

The team played all of their home games this season at Pasig Sports Center. The Pasig-based team would move to Ynares Sports Arena in future seasons.
