'''Foursquare'''是一个提供用户定位的[[社交網絡服務]]，它提供[[移动设备]][[软件]]和[[电脑游戏|游戏]]。用户可以使用[[移动设备]]或通过发送消息等方法，在某个实际的地点“登入（{{lang|en|check-in}}）”<ref>{{cite web | language =  | publisher = 华盛顿邮报 | title = SXSW: Foursquare Scores Despite Its Flaws | url = http://www.washingtonpost.com/wp-dyn/content/article/2009/03/18/AR2009031802819.html | author =  | date =  | accessdate =  | archive-date = 2017-11-06 | archive-url = https://web.archive.org/web/20171106083357/http://www.washingtonpost.com/wp-dyn/content/article/2009/03/18/AR2009031802819.html | dead-url = no }}</ref>。每次使用者在新地點報告時，他們便可以拿到數位獎品或是數位徽章作為獎勵。未來有機會對兌換成實質商品。服务的创始人是{{維基數據鏈接|Q1189061}}和{{維基數據鏈接|Q4553231}}。Foursquare曾被[[互联网]]巨头[[雅虎公司]]以1亿2500万美元的价格求购，但未实现交易<ref>{{cite news

从2011年开始，每年的4月16日是[[纽约市]]的“Foursquare日”<ref>{{cite news|title=纽约市长宣布4月16日为“Foursquare日”|url=http://tech.sina.com.cn/i/2011-04-15/03585408183.shtml|accessdate=2011-04-15|newspaper=新浪科技|date=2011年4月15日|archive-date=2011-04-20|archive-url=https://web.archive.org/web/20110420002029/http://tech.sina.com.cn/i/2011-04-15/03585408183.shtml|dead-url=no}}</ref> 。

== 中国大陆封锁 ==
2010年6月4日，Foursquare被中国大陆[[防火长城]]封锁。媒体猜测的原因是当天有大量中国用户在[[天安门广场]]签到并发布关于[[六四事件]]的言论。<ref>{{cite web |url=http://news.cnet.com/8301-13577_3-20006814-36.html |title=China's Foursquare block tied to Tiananmen Square |publisher=CNET News |date=2010-06-04 |accessdate=2010-11-15 |archive-date=2010-06-05 |archive-url=https://web.archive.org/web/20100605134518/http://news.cnet.com/8301-13577_3-20006814-36.html |dead-url=no }}</ref>

2011年，Foursquare技术变更，更换IP地址及缺省使用[[HTTPS]]，中国恢复可直接访问。
