在美国，公开持武（英语：open carry）是指「在公共场所公开地持有武器」，与之对应的是隐秘持武，即指以观察者看不到的方式携带武器。

枪支持有者在他们日常生活中公开持武的现象最近几年在美国有增加的趋势。。已经有若干的活动用来增加空开持武的可见度和公众对此的意识。公开持武的支持者通过历史和统计指出，犯罪分子通常会隐匿他们的武器，这与守法公民自豪展示他们的武器形成鲜明的对比。受到例如OpenCarry.org、GeorgiaCarry.org和一些参加自由州计划人士的推动，公开持武最近几年开始复兴。但是目前还不清楚这是否只是一个短期的现象。

In the United States, open carry refers to the practice of "openly carrying a firearm in public", as distinguished from concealed carry, where firearms cannot be seen by the casual observer.

The practice of open carry, where gun owners openly carry firearms while they go about their daily business, has seen an increase in the U.S. in recent years. This has been marked by a number of organized events intended to increase the visibility of open carry and public awareness about the practice. Proponents of open carry point to history and statistics, noting that criminals usually conceal their weapons, a stark contrast to the law-abiding citizens who display their sidearms. Encouraged by groups like The Modern American Revolution, OpenCarry.org, GeorgiaCarry.org and some participants of the Free State Project, open carry has seen a revival in recent years, but it is not yet clear if this represents just a short-term trend.
