probably a nebula. A nebula is an interstellar cloud of dust, gas and plasma. Originally nebula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy is sometimes referred to as the Andromeda Nebula). They surround galaxies and help form new stars.

Probably a galactic cluster, which is essentially a cluster of galaxies. They can be extremely large.
There is something called a supercluster which is essentially an unimaginably big cluster of galactic clusters.
They can be as large as 1 billion light years across and can move at over 2 million miles per hour!
Just when you thought the great wall of china was long. The Great wall of Sloan is over a billion light years across!

If by an "object" you mean something continuous (which disqualifies galaxies and groups of galaxies), then the largest, by mass at least, must be one of the black holes which are the centres of most galaxies (including ours) and provide the gravity forces that hold the galaxies together.

There is a star in our galaxy called Eta Carinae that is 150 times as massive as our sun and is the biggest star know. Its expected to explode at any time in a titanic supernova that will be clearly visible from earth, even during the day.

I’ve googled this & found it to be a ‘Giant Blob’ - not a joke, look at the links.
It’s a colossal structure 200 million light-years wide & is about 12 billion light years away…so it was around about 12 billion years ago.

I believe there are superclusters as well, but if you mean a single object, that's hard to say.
You would have to define what knid of object - I'm not sure what the giant blob is, but there may be single "pockets" of gas that span light-years.

the largest single objects, are the black holes at the centre of every universe.

Ted Kennedy- although I am aware that Val Kilmer might be approaching the same size/mass!

Not including the universe, the milky way--our galaxy--is the largerst star cluster we are aware of
