伊恩·萨默海尔德（Ian Joseph Somerhalder），美国男演员，因在《吸血鬼日记》里扮演吸血鬼两兄弟中代表邪恶化身的哥哥达蒙·萨尔瓦托(Damon Salvatore)而广为人知，此外还扮演过美国广播公司悬疑类电视连续剧《迷失》的角色之一布恩·卡利斯尔（Boone Carlyle）。
The son of a massage therapist and a building contractor, Somerhalder was born and raised in the small southern town of Covington, LA. Boating, swimming, fishing and training horses filled much of his recreational time growing up, as did the school drama club and performing with the local theater
group. With his mother's encouragement, at age 10 he began a modeling career that took him to New York each summer. By junior high, he opted to put modeling on the back burner and focus more on sports and school. A few years later, when the opportunity to model in Europe arose, Somerhalder grabbed it, embarking on an enriching path of work, travel and study that took him to cities including Paris, Milan and London. At 17, he began studying acting in New York, and by 19 had committed himself to the craft, working with preeminent
acting coach William Esper. His fate was sealed while working as an extra in a club scene in the feature film _Black & White(1999)_. A talent manager visiting a client on the set spotted Somerhalder in a crowd scene of 400 and immediately signed him for representation. Happy to be anchored in New York, Somerhalder spends much of his time studying acting, writing and practicing yoga. His recreational
interests include water and snow skiing and horseback riding.
