杰克 (jié kè) is the standard Mandarin phonetic transliteration of the English name Jack. 杰 means outstanding or hero (杰出, outstanding) and 克 means to overcome or a unit of weight. Together they are chosen for their sound rather than meaning, as is common in Chinese name transliterations. It appears in film, literature, and media where English characters named Jack appear (杰克·伦敦, Jack London; 泰坦尼克号的主角, the Titanic protagonist).
