Paayum Puli was released on 14 January 1983, coinciding with Pongal.[13][14] Thiraignani of Kalki said the real pouncing tigers of the film were the hero and the technicians.[15]Paayum Puli was a commercial success, completed a 133-day run at theatres and grossed over ₹20 million (equivalent to ₹340 million or US$4.0 million in 2023).[16][17]
The makers wanted to release the film in Sri Lanka, but got into trouble as the title had "Puli" (Tiger), perceived as alluding to the Liberation Tigers of Tamil Eelam. It was decided to release the film in the country with the title Irumbu Karangal (transl. Iron hands), but the film still did not release there.[18]
