Tina Lim Xin Ying[a] (Chinese: 林欣莹; pinyin: Lín Xīnyíng) was a 14-year-old student who was last seen in Choa Chu Kang, Singapore on 22 June 2002.

[2] According to Lim, at the time of her disappearance, she had only $10 in her wallet, did not bring any clothes with her, and her passport was still at home, which made it very unlikely that she had planned to run away.

When he could not find Tina in Singapore, he continued his search in neighbouring Malaysia, in areas including Penang, Ipoh, Sarawak, and even the border with Thailand.

On 1 November, the last day of the funeral wake, the family received several mysterious phone calls.

In 2004, the disappearance of Tina Lim was portrayed on Singaporean television series Missing on the fourth episode of its first season.
