CFOP（又称弗雷德里奇法（Fridrich Method））是速解魔方最常用的公式系统之一，由底十字（Cross）、下两层（F2L，First 2 Layers）、顶层定向（OLL，Orientation of last layer）、顶层排列（PLL，Permutation of last layer）四个步骤组成。最早由杰西卡·弗雷德里奇总结。自2005年以来，大多世界排名在前十名的魔方玩家都使用CFOP公式或它的变种。

The CFOP Method (Cross - F2L - OLL - PLL), sometimes known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3x3x3 Rubik's Cube. This method was first developed in the early 1980s combining innovations by a number of speed cubers. Czech speedcuber Jessica Fridrich is generally given credit for popularizing it by publishing it online in 1997.
