It was/is a thing in some countries: https://en.wikipedia.org/wiki/University_constituency#Irelan...

But the Irish Senate has a relatively unusual composition and voting system anyway: https://en.wikipedia.org/wiki/Seanad_%C3%89ireann#Compositio...

For the upper house, yes.

As a graduate of an institute of technology, having transferred from a university, I don’t get to vote in the Seanad (senate) elections at all.

To clarify: most upper house seats are elected by members of parliament. There’s a pool of seats reserved for graduates of a subset of universities to vote on.

It’s terribly undemocratic and needs to be reformed or abolished.

For one particular pool of candidates fighting over university allocated senate seats - you still have regular voting rights.
