R adalah bahasa pemrograman dan lingkungan perangkat lunak bebas untuk komputasi statistik dan grafik yang didukung oleh R Foundation for Statistical Computing. Bahasa R banyak digunakan di kalangan ahli statistik dan data miner untuk mengembangkan perangkat lunak statistik dan analisis data. Jajak pendapat, survei penambangan data dan studi basis data literatur ilmiah, menunjukkan peningkatan popularitas yang cukup besar dalam beberapa tahun terakhir. Pada Agustus 2018, R peringkat ke-18 dalam indeks TIOBE, ukuran popularitas bahasa pemrograman.
Paket GNU, source code untuk lingkungan perangkat lunak R ditulis terutama di C, Fortran dan R sendiri dan tersedia secara gratis di bawah GNU General Public License. Versi biner pre-compiled disediakan untuk berbagai sistem operasi. Meskipun R hanya menggunakan command line interface, ada beberapa antarmuka pengguna grafis, seperti RStudio, lingkungan pengembangan terintegrasi.
