Abstract
The topological field theories associated with affine Lie superalgebra s are constructed. Their BRST symmetry is characterized by a Kazama al gebra containing spin 1, 2 and 3 operators and closes linearly. Under this symmetry all operators are grouped into BRST doublets. The relati on between the models constructed and noncritical string theories is e xplored.
