In Jainism, the term Shasanapati (शासनपति) refers to the "head of the Jain order" or the spiritual leader who is responsible for maintaining and administering the religious order during a particular time period. This position is not always formally designated in all Jain sects, but traditionally, it is understood that during each time cycle (ārā), there is a Shasanapati who upholds the Jain dharma.

Currently (as of the present era), in the context of Jain universal history, Lord Mahavira (the 24th Tirthankara) is considered the Shasanapati of the present cycle (Avasarpini). After the Nirvana of a Tirthankara, the Shasan (religious order) continues through the teachings and guidance of Acharyas, Upadhyayas, and other spiritual leaders, but there is no single universally recognized Shasanapati after the Tirthankara.

Within specific Jain sects or traditions, prominent Acharyas or monks may be informally regarded as the spiritual heads, but from a doctrinal and historical perspective, the Vartaman (current) Shasanapati is Mahavira Swami.

Summary:

• Vartaman Shasanapati (Current Head of Jain Order): Bhagwan Mahavira (according to Jain doctrine)
• After Mahavira’s Nirvana, the leadership is maintained by Acharyas and monks, but no one holds the universal title of Shasanapati as Mahavira did.
