There are a lot of those. They can be recognised by name (having both "hydroxy" and "-oic acid").
Explanation:
The simplest is glycolic acid, (UPC-name: hydroxy ethanoic acid).
One you may know from everyday life is lactic acid, or officially:
2-hydroxy propanoic acid.
Citric acid is another one (but that has three acid groups).
