Lanchhan (lakshan) Jain dharm me un Tirthankaron ke nishan ya chinh hote hain jo har ek Tirthankar ke saath juda hota hai. In chinhon ka upyog jain samudaay ke logon ke liye us Tirthankar ko pehchanne, unki jaankari ya smaran ke liye kiya jata hai.

• Har Tirthankar ke liye ek vishesh lanchhan hota hai, jise murtiyon, chitrakon, mandiron ki pratimaon par dekha ja sakta hai.
• Lanchhan ka upyog pratyek Tirthankar ki pehchan aur unki aagamikta (kalyaan) ki yaad dilaane ke liye hota hai.
• Digambar aur Shwetambar dono paramparaon me lanchhan ki adhikaarik suchi hoti hai, lekin kuch chhoti-moti details ya chinhon ki pehchaan dono me thodi alag ho sakti hai.

Aap chahein to main a specific Tirthankar ke lanchhan ki poori suchi (Digambar aur Shwetambar dono ke saath) de sakta/ sakti hoon.
