A floor tom is a large drum with two heads that usually sits on the floor using three legs. It can also be attached to a cymbal stand with a clamp or held up by a rim mount. The drum is shaped like a cylinder and does not have snare wires. It makes a deep, rich sound that can change in pitch. It is similar to the tenor drum in marching bands and classical music.

Floor toms are the lowest-pitched drums on a regular drum set and are played with sticks. Common sizes include 16×16 inches.

The floor tom became popular in the 1950s when drummer Gene Krupa used a 16×16 model. Some drummers, especially in jazz, use floor toms as small bass drums by mounting them horizontally on special racks. Companies like Pearl now sell kits that let drummers convert floor toms into bass drums. These kits include rods that replace the legs to stand the drum upright horizontally. Drummers often use bass drum hoops to finish the conversion.

Floor toms are also used in parades, where they are carried and struck for effect. They can replace surdo drums in samba and bossa nova music. These drums are also found in jazz band drum kits.
