Punchi Banda Elangasinha, Rate Mahatmaya (Sinhala: පුංචි බණ්ඩා ඉලන්ගසිංහ; 6 April 1888 – 22 September 1960) was a Sri Lankan notary public, traditional eye doctor, astrologist and musicologist.

He pioneered and served as the president of "Samastha Lanka As Weda Sangamaya‟ (All Island Society of Traditional Eye Doctors) and "Samastha Lanka Sarpa Visha Veda Sangamaya‟ (All Island Society of Traditional Venom Doctors).

[2] Elangasinha was selected to be a part of Lanka Gandharva Sabha's judging panel, along with SLB Kapukotuwa, Dr.OHD Wijesekera, Lionel Edirisinghe, Mudliyar EA Abeysekera and LLK Gunatunga to determine the country's national anthem.

[3][4] In a controversial decision, the song written by P. B. Elangasinha and set to music by Lionel Edirisinghe was announced to be the new National Anthem.

[5] While the song itself was flawless and above reproach it was the perception of favoritism in the decision to adopt it that fueled criticism and protests.
