Lawrence Chongson (September 23, 1963 – December 26, 2021) was a Filipino basketball coach.
Chongson served as an assistant coach to Alfrancis Chua at Tanduay Rhum Masters in the PBA. After the teams disbandment, he served as head coach of Pangasinan Waves in the Metropolitan Basketball Association.[1] In the semi-pro Philippine Basketball League, he coached some teams such as Air Philippines, its successor franchise Bacchus Energy Drink Raiders,[2] [3] and Mail and More Comets[4] [5] [6] [7] (later known as Burger King Stunners).
He coached the UE Red Warriors for two seasons, and on his first season, he led the Paul Lee-led Warriors to the Finals, after defeating Andy Barroca and the FEU Tamaraws without twice-to-beat advantage. But the team lost to Norman Black-coached Ateneo Blue Eagles in three games. In 2011, he was replaced by former Red Warrior and PBA legend Jerry Codiñera.[8]
He later coached D-League team Tanduay Light Rhum Masters, and returned to UE as their assistant coach, and consultant under Bong Tan in 2019.[9] [10]
