T-cell lymphoma describes several different types of Non-Hodgkin lymphoma which affect T cells. T cells are involved in four classes of lymphoma. Together with lymphomas involving NK cells, these account for perhaps one in eight cases of NHL.cite web |url=http://www.leukemia-lymphoma.org/attachments/National/br_1161891669.pdf |title=The Lymphomas |accessdate=2008-04-07 |author= |authorlink= |coauthors= |date=May 2006 |format=PDF |publisher=The Leukemia & Lymphoma Society |pages=p. 12] The four classes are:

* Extranodal T cell lymphoma
* Cutaneous T cell lymphomas: Sézary syndrome and Mycosis fungoides
* Anaplastic large cell lymphoma
* Angioimmunoblastic T cell lymphoma

More information on various classification schemes is in the main lymphoma article.
