It is really too early to know; we know about some 400 planets, and our galaxy is expected to have many billions of them. However, the limit should be at about 13 times the mass of Jupiter; above that, it would no longer be a planet, but a brown dwarf.
A galaxy.
Most exoplanets are large gas giants, one of those is the largest known planet in the galaxy. If you meant the solar system, then the largest planet is Jupiter.

Jupiter is the largest planet in the Milky Way Galaxy. It is formed from gas and is also known as the Gas Giant
The order from largest to smallest is universe, galaxy, star, and planet. The universe encompasses everything, including galaxies like the Milky Way. Within galaxies, there are stars like our sun, and planets like Earth.

The order from largest to smallest would be: star, galaxy, planet, filament. Stars are individual astronomical objects, galaxies are collections of stars, planets are celestial bodies in orbit around stars, and filaments are structures in the cosmic web that connect galaxies.

The largest planet in the Milky Way galaxy is Jupiter. It is a gas giant with a mass more than 300 times that of Earth and is known for its Great Red Spot, a swirling storm that has been observed for centuries.
The galaxy is not a planet. The galaxy is MADE of millions and millions of stars and planets.
