Rebutia minuscula is a species of cactus from northern Argentina.^[1] It is the type species of the genus Rebutia.{{sfn|ps=|Anderson|2001|p=599}}

The status of the species of Rebutia is currently uncertain; indeed the genus as defined by Anderson (2001) has been shown to be polyphyletic.^[2] Anderson describes R. minuscula as consisting of globe-shaped stems with a diameter of up to {{convert|5|cm|in|abbr=on|0}}, forming large clusters. The stem has 16–20 ribs with small but distinct tubercles ("bumps"). Each areole produces 25–30 fine whitish spines, {{convert|1|-|3|mm|in|abbr=on|1}} long. As in other species of Rebutia, the flowers are not produced at the top of the stem, but from around the base. They are red, up to {{convert|4|cm|in|abbr=on|1}} long.^[1] Other sources include species such as R. marsoneri with yellow to orange flowers{{sfn|ps=|Anderson|2001|p=604}} in R. minuscula,^[3] giving the species a much broader range of flower colour.
