अक्का महादेवी (ಅಕ್ಕ ಮಹಾದೇವಿ) वीरशैव धर्म संबंधी कन्नड़ कविता में प्रसिद्ध हस्ती थीं। ये १२वीं शताब्दी में हुई थीं। इनके वचन कन्नड़ गद्य में भक्ति कविता में ऊंचा योगदान माने जाते हैं। इन्होंने कुल मिलाकर लगभग ४३० वचन कहे थे, जो अन्य समकालीन संतों के वचनों की अपेक्षा कम हैं। फिर भी इन्हें वीरशैव धर्म के अन्य संतों जैसे बसव, चेन्न बसव, किन्नरी बोम्मैया, सिद्धर्मा, अलामप्रभु एवं दास्सिमैय्या द्वारा ऊंचा दर्जा दिया गया है।
Akka Mahadevi (ಅಕ್ಕ ಮಹಾದೇವಿ) was a prominent figure of the Veerashaiva Bhakti movement of the 12th century Karnataka. Her Vachanas in Kannada, a form of spontaneous mystical utterances, are considered her most notable contribution to Kannada Bhakti literature. In all she wrote about 430 Vachanas which is relatively fewer than that compared to some other saints of her time. Yet the term 'Akka' (elder Sister), which is an honorific given to her by great Veerashaiva saints like Basavanna, Chenna Basavanna, Kinnari Bommayya, Siddharama, Allamaprabhu and Dasimayya, speaks volumes of her contribution to the spiritual discussions held at the Anubhava Mantapa. She is in hindsight seen as a great and inspirational woman for Kannada literature and the history of Karnataka. She is said to have accepted the god Shiva ('Chenna Mallikarjuna') as her husband, traditionally understood as the 'madhura bhava' or 'madhurya' form of devotion.
Born in Udutadi (or Udugani) near the ancient city of Banavasi (in Shikaripura taluk Shimoga district). She was born in 1130CE and lived until 1160.
She is considered Kannada’s first female poem writer (poetess)
