Vericon is an annual science fiction convention at Harvard University, organized by the Harvard-Radcliffe Science Fiction Association. Lasting over a three-day weekend, for the first nine years of its existence it took place on the last weekend of January; for 2010, however, it was moved to mid-March to accommodate changes in Harvard College's academic calendar. It has been described as the largest college-based science fiction convention in the United States. Vericon was held most recently in 2016, and is currently on hiatus.
