父爱主义（英语：paternalism或parentalism，又称父权主义、温情主义、家长式作风、家长式管治）是一种行为，由个人、组织、或国家，图以替一些人或群体的好处设想，去限制该些人或群体的自由或自主权。 家长作风也可以意味着该行为是对抗或忽视一个人的意志，或者该行为表现出优越感的态度。

通常指的是一个指导者（“父亲”）代表其他人（“妻子”或“儿子”）替他们作出“为他们好的”决策，即便这样的决策违背他们的愿望。简而言之，是“管你，是为你好”的思维。它是封建家长制遗留下来的作风。

Paternalism (or parentalism) is behavior by an organization or state which limits some person or group's liberty or autonomy for what is presumed to be that person's or group's own good. Paternalism can also imply that the behavior is against or regardless of the will of a person, or also that the behavior expresses an attitude of superiority.
