反照率特征（albedo feature）是行星、卫星等太阳系天体某个反照率和邻近区域相比特别高或低（即特别亮或暗）的区域。

在历史上，反照率特征最早在火星和水星上被观测到（通常也只是这两颗行星）。早期的行星表面图（例如乔凡尼·斯基亚帕雷利和欧仁·米歇尔·安东尼亚第所绘）只表示行星表面的反照率特征；直到太空探测器到达其他天体并可观测撞击坑等表面地理特征为止。

在火星和水星以外其他天体的反照率特征有时被称为 Regio。

对于大气层相当浓密的金星和土卫六而言，无法以平常的光学望远镜看到永久性的反照率特征，因为无法借此看到表面状况，只能看到大气层的云层和其他在大气层上方越过的状况。

An albedo feature is a large area on the surface of a planet (or other solar system body) which shows a contrast in brightness or darkness (albedo) with adjacent areas.

Historically, albedo features were the very first (and usually only) features to be seen and named on Mars and Mercury. Early classical maps (such as those of Schiaparelli and Antoniadi) showed only albedo features, and it was not until the arrival of space probes that other surface features such as craters could be seen.
