Lōmāfānu or Loamaafaanu, also known by the Sanskrit name Sasanam, are Maldivian texts in the form of copper plates on which inscriptions have been added. The oldest of these plates dates from the twelfth century AD.
Many Old Maldivian historical texts are found only in lomafanu form. The Divehi Akuru script used on the plates, was named "evēla akuru" by H. C. P. Bell. Bell claimed that it resembled medieval Sinhala script. According to the Isdū Lōmāfānu, monks from monasteries of the southern atoll of Haddhunmathi were brought to Malé and beheaded.
Besides the Lōmāfānu plates found in Haddhunmathi Atoll, one of the most important Maldivian copperplates is the Bodugalu Miskiy Lōmāfānu found in Male'.
