北美少年爱好协会（The North American Man/Boy Love Association，NAMBLA）是美国一个以「促使禁止男人与男孩间发生性关系的法律自由化」为宗旨的非法组织。主要据点是美国旧金山与纽约。NAMBLA还呼吁议会立法或修法使儿童能在「不受性骚扰与性剥削的前提下拥有性的权利」，该组织宣称自己「没有任何事或人是违法的」、「不支持或鼓励任何想要转介援交的人士」。

NAMBLA每个月会在全美各地举行例会，每年在纽约还会举行一次全国大会。据1980年代初的报导称，该组织有超过三百名成员，其中甚至有知名人士如诗人艾伦·金斯堡与作家塞谬尔·迪兰尼为其立场辨解。在这之后NAMBLA的组织规模一直都是秘密，但根据一份联邦调查局的秘密调查文件显示，该会在1990年代中期时已有1100人的规模。最后在1995年时，NAMBLA因受到美国舆论的强烈批判与执法部门的扫荡而瓦解。现在该组织的全国总部只在旧金山留下几个极少回应的联系信箱。

The North American Man/Boy Love Association (NAMBLA) is a pedophile and pederasty advocacy organization in the United States. It works to abolish age-of-consent laws criminalizing adult sexual involvement with minors and campaigns for the release of men who have been jailed for sexual contacts with minors that did not involve coercion. The group no longer holds regular national meetings, and as of the late 1990s—to avoid local police infiltration—the organization discouraged the formation of local chapters. Around 1995, an undercover detective discovered there were 1,100 people on the organization's rolls. In 1997, NAMBLA was the largest group in IPCE, an international pro-pedophile activist organization. Since then, the organization has dwindled to only a handful of people, with many members joining online paedophile networks such as DanPedo, BoyChat, and Annabelleigh, according to Xavier Von Erck, director of operations at the anti-pedophile organization Perverted Justice. As of 2005, a newspaper report stated that NAMBLA was based in New York and San Francisco.
