The transversospinales are a group of muscles of the human back. Their combined action is rotation and extension of the vertebral column. These muscles are small and have a poor mechanical advantage for contributing to motion. They include:
- the three semispinalis muscles, spanning 4-6 vertebral segments
- multifidus, spanning 2-4 vertebral segments
- rotatores, spanning 1-2 vertebral segments
- rotatores cervicis
- rotatores thoracis
- rotatores lumborum
