斯蒂芬妮娅(英语:Stefania)是金星北部赛德娜平原上的一个撞击坑,直径11公里(6.8英里),它是金星上较小的撞击坑之一,因为大部分小流星在通过金星稠密的大气层时都会解体,所以,金星上没有直径低于3公里(1.9英里)的陨石坑,甚至连直径在25公里(16英里)以下的陨石坑也相对稀少。喷射物分布情况表明,撞击体是以一个倾斜的角度撞击地表,经仔细观察可认定该撞击坑为二级撞坑,即由主撞击坑喷发的块状物撞击形成的次级陨坑。关联该类撞击坑及其它很多金星撞击坑的特征是雷达暗晕,由于雷达回波暗代表表面光滑,因此,这被假设为强烈的冲击波清除或粉碎了先前粗糙的地表材质,或者在碰撞发生期间或之后,被更细小的沉积物所覆盖。
