The invention discloses a method and a device for detecting a phishing website. The method comprises the following steps that: a client obtains the URL to be detected of the accessed website, and detects the URL to be detected of the accessed website to obtain a client detection result, and the client detection result expresses the correlation degree of the accessed website and the phishing websites; the client sends the URL to be detected to a server, and receives the server detection result obtained by detecting the URL to be detected, which is sent by the server, and the server detection result expresses the correlation degree of the accessed website and the phishing websites; the client carries out a comprehensive judgment on the URL to be detected according to the client detection result and the server detection result, so as to judge whether the URL to be detected belongs to the phishing websites. The method and the device disclosed by the invention are capable of improving the accuracy of detecting the phishing websites.
