Lanchhan ka matlab Jain dharm me Tirthankar ka pratīka (emblem) hota hai. Har Tirthankar ka apna ek vishesh lanchhan hota hai, jo unki murti, chitr ya manuskriti par dikhaya jata hai. Ye lanchhan batata hai ki kis Tirthankar ki murti hai.

• Lanchhan ka uddeshya: vishesh Tirthankar ki pehchan karna, aur unke gunon ya kahaniyon ki yaad dilana.
• Digambar aur Shwetambar dono paramparaon me lanchhan ki pehchan hoti hai, lekin kuch lanchhan ki chhoti-moti vyakhya ya chitrankan dono darshanon me thodi alag ho sakti hai.
• Aksar mandiron ki pratimaon, lekhon aur muralon me yeh lanchhan dikhai dete hain.

Agar aap chahen to main aapke liye specific Tirthankar ke lanchhan ki list (Digambar ya Shwetambar ke hisaab se) de sakta/ sakti hoon.
