Libby Squire's family joined staff and students at Hull University to remember the 21-year-old who's body was discovered in the Humber Estuary.
Tributes were read and a minute's silence was held outside the Brynmor Jones Library on the campus. The vice chancellor of the university and the president of the students union addressed the crowds.
Those who attended the event then made the short walk over to a tree at the university, where flowers for Libby were laid.
Earlier, an inquest into Libby's death was opened and the coroner Professor Paul Marks was told how the student was identified by her fingerprints. Police also confirmed they are treating her death as a homicide.
Det Supt Martin Smalley said they were still acquiring pathological and forensic evidence and so were unable to release the body back to the family for burial.
The inquest was adjourned until a future date which is yet to be confirmed.
Libby, who studied philosophy and was described as a popular student, was found dead in the Humber Estuary last Wednesday afternoon.
