Martanda Cinkaiariyan (Tamil: மார்த்தாண்ட சிங்கையாரியன்) (died 1348) ascended the throne of Jaffna Kingdom under the throne name Pararasasekaram III. He is one of the early Aryacakravarti kings about whom historical and epigraphical evidence is available. He was noted by Ibn Battuta in his well-known travelogue as well as he has left behind a few inscriptions. He oversaw the international trade of the Jaffna kingdom with Yemen via the kingdom's powerful trading ships. Martanda Cinkaiariyan accompanied Battuta to the peak of Sivanoli Padam Malai along with Yogis and other Hindus and companions of the king who visited the sacred Shiva site annually.

Ibn Battuta, a Moroccan traveller described his rule in his travelogue. Ibn Battuta mentions that the King had a large navy, and was seen trading in pearls, cinnamon and ahil and had cordial relationship with Indian rulers. In his travelogue it was noted that the king has encamped in the Puttalam are where he had his seasonal capital. He was encamped due to the pearling season.

The primary source such as Yalpana Vaipava Malai records that Martanda was forced to subdue Vanniar chieftains from the Vanni region who had rebelled against him. An inscription dated in the 3rd regnal year of Vikramabahu III (1357–1374), found at the Medawala Rajamaha Vihara in the Kandy District records a treaty between that king and an Aryacakravarti named Martanda (Sin ai Ariyan) of Jaffna. In the Medawala inscriptions of 1359 found near a bo-tree at Medawala in Harispattuva reveals that Martanda appointed tax collectors to collect taxes from the villages of Sinduruvana, Balawita, Matale, Dumbara and Sagamathunarata which belonged to the Gampola kingdom.
