哇嘎（Vagaa）是一套由中国大陆公司开发、基于eDonkey网络及BitTorrent协议的点对点（P2P）软件，主要用于下载大型的电影、游戏或电视剧文件，又或是网络环境比较复杂，例如透过NAT、NAPT等协议的网接环境。

根据哇嘎的网站介绍，这套软件「致力于对等互联网的建设和运营，帮助大众享受宽带互联网所带来的便利和快捷。无论是电影、音乐、动漫还是游戏、电视节目，只要下载并安装Vagaa哇嘎，您的电脑将变成通连全球的互动娱乐中心。」它利用了特别的软件路由进程库，使上传及下传的速度得以加快，即使双方用户都在NAT环境；而Vagaa的附带搜索功能亦很强劲，亦支持多语环境。但事实上，有用户指这套软件由于设计上的疏忽，会对服务器不断发出攻击，因此有伺服管理员会拒绝来自Vagaa用户的链接，而网络管理员亦有时对软件的交通封锁，以防止局域网被拖垮。

Vagaa (Chinese:哇嘎) is a peer-to-peer program originating from Mainland China. The software is compatible with eDonkey network and BitTorrent and can be used for downloading large files, however as it has been blocked from most eDonkey servers, its usefulness has dropped in the past years. The software is being developed by users from Mainland China and has special support for some techniques utilized on complicated LANs.
