吉恩·特雷尔·威廉姆斯二世（Guinn Terrell Williams Jr.，1899年4月26日－1962年6月6日）是一位美国演员，曾出演过《道奇城》（1939年）、《圣达菲小径》（1940年）和《科曼奇人》（1961年）等令人难忘的西部片。他被称为“大男孩”（Big Boy），因为他身高6英尺2英寸，且多年在牧场工作以及打半职业和职业棒球锻炼出了健硕的体格。在其电影生涯的巅峰时期，他的名字在海报和电影片头中经常直接署名为“大男孩”威廉姆斯（“Big Boy” Williams），或吉恩·“大男孩”·威廉姆斯（Guinn "Big Boy" Williams）以及“大男孩”吉恩·威廉姆斯（“Big Boy” Guinn Williams）。
