Lately a lot of attention has been given to legal regulation of cybersecurity. This article will review legal regulation of cybersecurity in Lithuania. Historical retrospective of legal regulation of cybersecurity in Lithuania will be discussed, strategic Lithuanian cybersecurity documents will be analysed, and the Law on Cybersecurity of the Republic of Lithuania will be analysed and evaluated. After a comparative analysis of cybersecurity strategies and laws and a review of legal regulation of cybersecurity in Lithuania, gaps of law-making and of other measures were distinguished, and corresponding conclusions were made. The adoption of the new Law on Cybersecurity, which regulates many important institutes, is evaluated positively. But with regard to the current legal regulation on cybersecurity in Lithuania additional measures are necessary (functions of institutions that formulate cybersecurity policy and perform control functions have not been detailed and distinguished, also functions of the Lithuanian national Computer Emergency Response Team (CERT) are not foreseen in the Law on Cybersecurity, etc.).
