Yes. Jainism has sacred religious texts called Agamas and other respected scriptures.

Main points:

• Shwetambar Jain tradition recognizes the Agamas as the principal canonical scriptures.
• Digambar Jain tradition believes the original Agamas were lost in their full form, and gives great importance to texts such as Shatkhandagama, Kasayapahuda, Samayasara, and other works of great Acharyas.

Important Jain texts include:

• Tattvartha Sutra — accepted by both Digambar and Shwetambar traditions
• Agamas — especially important in Shwetambar tradition
• Uttaradhyayana Sutra
• Acharanga Sutra
• Sthananga Sutra
• Samayasara
• Pravachansara

So, yes — Jainism does have religious texts, and they guide Jain philosophy, ethics, vows, and spiritual practice.
