Dinamina (Sinhala: දිනමිණ) is a Sinhala language daily newspaper in Sri Lanka. It is published by the Associated Newspapers of Ceylon Limited (Lake House), a government-owned corporation. The newspaper commenced publishing in 1909. It was founded by the Sinhalese scholar H. S. Perera who acted as both owner and editor-in-chief of the paper at the outset. Upon Perera's death in December 1914, D. R. Wijewardena (who would later go on to become a prominent figure in the country's struggle for independence) bought out the company. It is now owned by the government of Sri Lanka.
