I argue that there is potential for collaborative work between science educators and citizenship educators. However, following comments about that potential, I raise a number of challenges. Those challenges relate to the public perception of science, narrow academic perspectives of some science educators, and problematic attempts to develop a form of science education that, at times, some have claimed is relevant to--or, even, a form of--citizenship education. The latter point is considered with reference to some science educators' perceptions concerning the nature of citizenship and citizenship education. I argue that the perceptions of some science educators seem to suggest significant differences in understanding from at least some of those who would regard themselves as citizenship education specialists. In the final main section of the article, I suggest, briefly, some ways in which further work to develop collaboration between science educators and citizenship educators could be considered.
