The 1999 PBA All-Filipino Cup or known as the 1999 McDonald's-PBA All-Filipino Cup for sponsorship reasons, was the First Conference of the 1999 PBA season. It started on February 7 and ended on June 6, 1999.
With a 7–0 start, Mobiline had a losing run to finish the elimination round. Being the #1 seed, they faced the ragtag Barangay Ginebra Kings with a twice to beat advantage.
The Kings managed to keep in step with the Phone Pals throughout the game; with Mobiline leading by one point in the closing seconds, Bal David converted a jump-shot as time expired that caused jubilation at the mostly pro-Ginebra crowd. Asi Taulava broke down and slumped to the bench right after David's game-clinching jumper and booked a flight to the United States the day after the game.
Barangay Ginebra would come up short in their playoffs run as the Zoom Masters swept them in their semifinals series, 3–0. Game 2 had a free-for all bench-clearing brawl that saw punches being thrown; Shell player Jay Mendoza instigated the fight when he elbowed Ginebra's Wilmer Ong. A total of ₱235,000 worth of fines were issued by PBA commissioner Jun Bernardino, the second-greatest amount since the 1990 Finals played ironically, by Shell and Ginebra where Ginebra walked out to hand Shell the championship trophy.
