It is Andromeda... about five times the size of the milky way. But not our closest galactic neighbor as commonly believed.

The Local Group is the group of galaxies that includes our galaxy, the Milky Way. The group comprises over 30 galaxies, with its gravitational center located somewhere between the Milky Way and the Andromeda Galaxy.
The two most massive members of the group are the Milky Way and the Andromeda Galaxy.
The Andromeda Galaxy is the larger of the two.
These two barred spirals each have a system of satellite galaxies.
The Milky Way's satellite system consists of Sag DEG, Large Magellanic Cloud, Small Magellanic Cloud, Canis Major Dwarf, Ursa Minor Dwarf, Draco Dwarf, Carina Dwarf, Sextans Dwarf, Sculptor Dwarf, Fornax Dwarf, Leo I, Leo II, Tucana Dwarf, and Ursa Major Dwarf.
Andromeda's system comprises M32, M110, NGC 147, NGC 185, And I, And II, And III, And IV, And V, Pegasus dSph, Cassiopeia Dwarf, And VIII, And IX, and And X.
M33, the third largest, and only ordinary spiral galaxy in the Local Group, may or may not be a companion to the Andromeda galaxy but probably has Pisces Dwarf as a satellite. The other members of the group are gravitationally secluded from these large subgroups.

G'day Toyelazio,
Thank you for your question.
Our group is called the Local Group. The two biggest galaxies within it are the Milky Way and the Andromeda Galaxy with the Andromeda Galaxy being the largest with one trillion stars.
These two barred spirals each have a system of satellite galaxies.
The Milky Way's satellite system consists of Sag DEG, Large Magellanic Cloud, Small Magellanic Cloud, Canis Major Dwarf, Ursa Minor Dwarf, Draco Dwarf, Carina Dwarf, Sextans Dwarf, Sculptor Dwarf, Fornax Dwarf, Leo I, Leo II, Tucana Dwarf, and Ursa Major Dwarf.
Andromeda's system comprises M32, M110, NGC 147, NGC 185, And I, And II, And III, And IV, And V, Pegasus dSph, Cassiopeia Dwarf, And VIII, And IX, and And X.
We are approaching the Andromeda Galaxy with the two galalxies colliding in a few billion years.
I have attached sources for your reference.
Regards

I believe the Andromeda Galaxy is larger than the Milky Way, so it would be Andromeda.
