In Jainism, a Kevalajñānī is a being who has attained Kevalajñāna, which means infinite, perfect, and absolute knowledge.

A Kevalajñānī:

• knows all substances, all modes, and all times directly
• is completely free from ignorance
• is free from attachment, hatred, and delusion
• has destroyed the ghāti karmas that cover knowledge
• is spiritually supreme in the world of embodied souls

In simple words, a Kevalajñānī is an omniscient soul in Jain Dharma.

Examples of Kevalajñānī include the Tirthankars after attaining omniscience.
