Does lamprey have notochord

Yes, lampreys possess a notochord, which is a flexible rod-like structure that provides support. As jawless fish, they are part of the group called agnathans, and their notochord serves as the primary skeletal support during their larval and adult stages. In lampreys, the notochord is retained throughout their life, unlike in many other vertebrates, where it is replaced by the vertebral column.
