Grammatidae is a small family of ray-finned fishes which were formerly placed in the order Perciformes but are now regarded as being incertae sedis in the subseries Ovalentaria in the clade Percomorpha.[2] They are commonly known as basslets. They are marine fish found in the tropical western Atlantic Ocean.[1]

They are characterized in part by a broken or absent lateral line. The largest species reach around 10 centimeters in maximum length.[1]

Some basslets are colorful and are kept in marine aquaria.[1]

There are two genera:[1]

A number of other species may be called "basslets", in particular members of Serranidae, where they may be called "fairy basslets".
