Alexander Charles Yoong Loong (simplified Chinese: 熊龙; traditional Chinese: 熊龍; pinyin: Xióng Lóng, (born 20 July 1976 in Kuala Lumpur), is a Malaysian Chinese race car driver of European and Han Chinese parentage.

Yoong began his career in saloon cars before moving into the Proton one-make series. He later raced in single-seater cars where he won the Malaysian Championship in 1995. He moved into Formula Renault in 1996 with help from sponsors but finished outside the top-10. Yoong consulted his father who believed his son would succeed in lower categories.
