The Students of Aberdeen group, which emulates social diarists Humans of New York, shared an open letter addressed to the university.
It wrote: "Mental health issues and their very serious consequences cannot be ignored and underfunded anymore."
Law student Emily Drouet was found in halls near to campus earlier this month, the Press and Journal reported.
Police said there were no suspicious circumstances surrounding her death.
A Students of Aberdeen spokesperson told HuffPost UK that the lack of adequate mental health services was a nationwide problem.
They said: "We would like to give credit to the counselling service and the support services at Aberdeen University for doing a lot with not a lot of resources.
"We realise that this is a nationwide problem and not just an issue at our institution. Something needs to be done."
They said they do not represent the student body in any official capacity.
The Labour leader said that all too often young people were being let down by a lack of adequate, easy to access services which maintained discretion on campuses.
Corbyn told a rally at Parliament in January: "Invest the money now, give the young people the support they need, they benefit, we as a society benefit."
A University of Aberdeen spokesperson said: "The wellbeing of our students and staff is of paramount importance to the University of Aberdeen and we are committed to offering the best support possible to all.
"Working closely with the Student Association, the University has a number of student support services in place to help students overcome any issues they may experience during their time at University."
They continued: "Including a Counselling Service which offers free, confidential counselling to all members of the University community, and the Aberdeen Students’ Nightline which is run by students for students and provides those who use it with an opportunity to talk anonymously about their concerns and to receive information and support every night during term time."
It said it was subscribed to Big White Wall which provides 24/7 online support for students experiencing mental health concerns.
