Sean Dave Geroy Ildefonso (born April 14, 2000) is a Filipino professional basketball player for the Abra Solid North Weavers of the Maharlika Pilipinas Basketball League (MPBL). He is the younger child of PBA great Danny Ildefonso, thus he is nicknamed "Dave I" in reference to "Danny I".
Ildefonso played for the Ateneo de Manila University Blue Eaglets in high school before transferring to National University in 2018 to play for the Bulldogs. In 2020, he went back to Ateneo where we would play the rest of his collegiate career.
He then began his professional career in 2023 in the Korean Basketball League (KBL), playing for the Suwon KT Sonicboom. In 2024, he was selected with the fifth overall pick by the NorthPort Batang Pier in the Philippine Basketball Association (PBA) season 49 draft.
