Given that Zoro is a pirate hunter turned pirate, he has been in many pirate battles, and while he has bested most of his enemies, some have actually gotten the better of him and completely outclassed him in battle in one way or another. It is rare for Zoro to be bested, but these individuals have actually managed to pull it off.

Buggy

Beat Zoro In Orange Town

While it might be hard for some fans to believe that Buggy managed to accomplish this incredible feat, it is absolutely true that Buggy defeated Zoro in battle once. When Buggy fought Zoro for the first time, he gave him the impression that he was chopped in half completely. However, using the power of his Devil Fruit, Buggy was able to sneakily stab him from the back and this completely took Zoro out of the battle.

In fact, Buggy could essentially have killed Zoro right there and then. He spared out his vitals on purpose, which just goes to show that not only did Buggy go easy on them, but he spared his life on purpose in this battle. Zoro lost this fight terribly.

Arlong

Was Overwhelmingly Stronger Than Zoro

Arlong terrorizing Nami - One Piece

Arlong is the former captain of the Arlong Pirates and the Fishman who terrorized the Konomi Islands for quite a while. In the Arlong Park Arc of One Piece, fans got to see Arlong and his forces being taken on by the Strawhat Pirates. Of course, fans know that Luffy ended up defeating Arlong, however, while Luffy was stuck in his own predicament, the Straw Hat Pirates were doing their best to hold off the captain of the enemy crew.

Specifically, Zoro and Sanji did their best against him, however, both of them failed. Zoro was essentially manhandled by Arlong, and much of that was down to the fact that he was no match for him, and that he was already carrying severe injuries from his battle against Mihawk. Regardless, Zoro lost in this battle and could very well have died right there had Luffy not saved his life.

Bartholomew Kuma

Defeated Zoro In Thriller Bark

Bartholomew Kuma has taken on Zoro on more than one occasion and has defeated him every time. The first time they fought was on Thriller Bark. Clearly, Zoro did well against him, however, he quickly realized that there was nothing he could do to defeat Kuma. As such, Zoro accepted that he was outclassed, and offered his own head instead of Luffy's. Kuma graciously accepted and put him through a test by giving him Luffy’s pain.

Of course, Zoro could not even scratch Kuma’s cyborg body, and that just went to show the difference in terms of overall strength. Had Kuma willed it, he could easily have killed Zoro right there, and this is yet another battle that Zoro lost.

Dracule Mihawk

Beat Zoro In Baratie

Perhaps the pirate that gave Zoro his most bitter defeat is Dracule Mihawk. These two individuals ended up fighting against each other in the Baratie arc of One Piece. There, Zoro had hope to defeat Mihawk and claim the title of the strongest for himself. Much to his surprise, Mihawk was far above his level. In fact, Mihawk used a pocket knife to defeat Zoro, despite him using all three of his swords.

In the end, Zoro was utterly humiliated and slashed across the chest, receiving a scar that he will carry for life. Mihawk could have killed Zoro, but he spared his life because he saw great potential in him. Mihawk has, since then, decided to wait for Zoro at the top so that he could one day come to challenge and surpass him.

Kaido

Beat Zoro In Wano

The most recent pirate to defeat Zoro in battle is none other than Kaido. On the rooftop of Onigashima, Zoro and the Worst Generation members fought against the monstrous Kaido. While Zoro certainly did perform well against him, landing some impressive blows, eventually, he could not stand up to the might of the Yonko.

Specifically, after Zoro launched his ultimate attack, Dead Man's Game, and scarred the Yonko, Kaido decided to go serious and unleashed his own powerful attack on him. Using his Conqueror's Haki, Kaido utilized a powerful Thunder Bagua and took out both Zoro and Law at the same time. Zoro was already weakened from Hakai at the time, and taking on a Thunder Bagua on top was impossible for him. Zoro ended up losing all senses and passed out immediately. Impressively enough, Law was able to sustain this attack and maintain his senses. Luffy woke up soon after and asked Law to go downstairs and help out there, promising that he would defeat Kaido by himself. This is when Zoro was taken by Law after his bitter defeat at the hands of Kaido and he then went on to fight against King, a battle that he barely won.
