Lisensi ISC adalah sebuah lisensi perangkat lunak bebas permisif yang diterbitkan oleh Internet Software Consortium, sekarang disebut Internet Systems Consortium (ISC). Secara fungsional setara dengan lisensi BSD yang disederhanakan dan MIT, tetapi tanpa bahasa yang dianggap tidak perlu setelah Konvensi Bern.[nb 1][nb 2]
Awalnya digunakan untuk perangkat lunak ISC seperti BIND dan dig, lisensi ini telah menjadi lisensi pilihan untuk kontribusi ke dalam proyek OpenBSD[6] dan menjadi lisensi baku untuk paket-paket npm.[7][8] Lisensi ISC juga digunakan untuk driver nirkabel Linux yang disumbangkan oleh Qualcomm Atheros.[9]
Ketentuan lisensi ISC adalah sebagai berikut:

Ketika awal rilis, lisensi ISC tidak memasukkan ketentuan "and/or", yang kemudian ditambahkan oleh ISC pada tahun 2007.[11] Paul Vixie menyatakan di milis BIND bahwa lisensi ISC mulai menggunakan ketentuan "and/or" untuk menghindari kontroversi serupa seperti peristiwa penolakan Universitas Washington untuk mengizinkan distribusi perangkat lunak surel Pine.[11]
Proyek OpenBSD mulai menggunakan lisensi ISC pada tahun 2003, sebelum ISC menambahkan ketentuan "and/or".[12] Namun, Free Software Foundation mengklaim bahwa OpenBSD "memperbarui" lisensi untuk menghapus ketentuan yang tidak perlu.[2]

Theo de Raadt dari OpenBSD, memilih untuk mempertahankan kata-kata yang awalnya digunakan oleh Universitas California, Berkeley, yang memungkinkan redistribusi bebas dalam perangkat lunak tidak bebas ataupun sumber terbuka.[5] Kedua lisensi tersebut dianggap dapat diterima oleh Free Software Foundation, dan kompatibel dengan GNU GPL.[2]

... This is a lax, permissive free software license, and compatible with the GNU GPL. ... This license is sometimes also known as the OpenBSD License, although there is one minor difference between the two licenses. The OpenBSD license was updated to remove the ambiguous term: "and/or". ... At the time the ISC license was released, the use of "and/or" construct was a concern because it is similar language used in the license of Pine that the University of Washington later claimed prohibited people from distributing modified versions of the software. ...
