可录光盘（英语：compact disc-recordable, CD-R）是一种可单次录写的唯读记忆光盘。

早期的可录光盘用银作涂层，容量只有650MB。后来推出保存期更长、用金作涂层的可录光盘。不过由于后来金的价格不断上涨，使生产商想尽办法制作涂层更薄的盘片。

后来有机化学技术的进展，使可录光盘可以无需采用金或银作涂层，而且使较高容量的可录光盘(700MB)生产更划算。现时（2009年）在香港，一般牌子的可录光盘只需要大约1港元就可以买到，使可录光盘变得极为普遍。

CD-R (Compact Disc-Recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times.

CD-R disks (CD-Rs) are readable by most plain CD readers, i.e., CD readers manufactured prior to the introduction of CD-R. This is an advantage over CD-RW, which can be re-written but cannot be played on many plain CD readers.
