Ukrainian decommunization laws refer to four Ukrainian laws of 2015. These laws relate to decommunization as well as commemoration of Ukrainian history. Such laws have been referred to as "memory laws". As a result of the law mandating the removal of communist-era monuments, and renaming places named after communist themes Ukraine's toponymy was radically altered and the face of whole cities changed. More than 51,493 streets, squares and "other facilities" have been renamed. Various major cities and many villages were renamed.
