国家美式足球联会（National Football Conference，简称NFC或国联）是美国国家美式足球联盟两联会其中之一。

国家美式足球联会与美国美式足球联会（AFC，美联）在1970年创立。国联在那年有13支球队，在合并之前皆属于NFL之下。不久，原AFL的球队和NFL的克里夫兰布朗、匹兹堡钢人和之后的巴尔的摩乌鸦加入了美国美式足球联会。

在合并之时国联有五种划分球队分区的方法。最终计划是从玻璃球中抽出。在以下这些计划里，计划三中选。

合并之后，三个扩充球队陆续加入了国联，达到现在的16队规模。当西雅图海鹰和坦帕湾海盗于1976年加入NFL时，他们暂时在转换联会前分别分在国联跟美联里一季。海鹰因2002年编制转回国联。卡罗来那黑豹在1995年加入国联。

The National Football Conference (NFC) is one of the two conferences of the National Football League (NFL), the highest professional level of American football in the United States. This conference and its counterpart, the American Football Conference (AFC), currently contain 16 teams each, making up the 32 teams of the NFL. Both conferences were created as part of the 1970 merger with the rival American Football League (AFL), with all ten of the former AFL teams and three NFL teams forming the AFC while the remaining thirteen NFL clubs forming the NFC. A series of league expansions and division realignments have occurred since the merger, thus making the current total 16 clubs per each conference.
