Which Episode Luffy Use Supreme Haki -
The term "Supreme King Haki" likely originates from a fan translation or confusion with Haoshoku (覇王色, "Supreme King/Conqueror Color") itself. In Japanese, Haoshoku Haki literally means "Supreme King Color Haki." Thus, referring to a technique as "Supreme King Haki" is redundant—it would be like calling a specific sword swing "Samurai Sword."
The correct canonical hierarchy, as established by Silvers Rayleigh and detailed in Vivre Card databooks, is:
Luffy does not achieve the latter until the Wano Country Arc.
No episode of One Piece features Luffy using "Supreme King Haki" because the term is non-canonical. However, the technique most fans intend—the infusion of Conqueror's Haki into physical attacks—first appears in Episode 1071 as a single, instinctive blow, and is first mastered and sustained in Episode 1074.
For a definitive answer to the spirit of your query: Watch Episode 1074. It is the moment Luffy transitions from a Conqueror who merely intimidates to a "Supreme King" who fights as one.
In the One Piece anime, Monkey D. Luffy unleashes his "Supreme King Haki" (also known as Conqueror’s Haki) in two distinct and iconic moments.
Here is a breakdown of why these episodes are the answer you are looking for. which episode luffy use supreme haki
The specific episode you are looking for is Episode 1028 of One Piece.
Context: The battle on the Skull Dome rooftop. Luffy, Zoro, Law, Kid, and Killer are fighting Kaido and Big Mom simultaneously. After recovering from his first defeat, Luffy realizes that Kaido's terrifying power doesn't come from physical punches, but from coating his body in Supreme Haki.
The Moment: Around the 18-minute mark of Episode 1028, Luffy stares down Kaido. He stops trying to punch with physical strength. Instead, he channels his willpower into his fist. Black, thick lightning (visually distinct from Armament Haki) begins to coil around his arm without him touching anything.
He throws a punch at Kaido. The punch does not touch Kaido’s face. It stops a millimeter away, but the force of the Supreme Haki blasts through Kaido’s skull, causing the Yonko to spit up blood and feel genuine pain for the first time in decades.
Keyword Answer: Yes, Episode 1028 is the episode where Luffy uses "Supreme Haki" in its advanced, offensive form.
It is important to note: Gear 5 (Episode 1071) is not Supreme Haki. Gear 5 is the awakening of Luffy's Devil Fruit (Hito Hito no Mi, Model: Nika). However, Luffy combines Gear 5 with his Advanced Supreme Haki in later episodes (1076+), creating the most powerful version of the character seen to date.

When asking "which episode does Luffy use supreme haki," fans are really asking, "When does Luffy become a top-tier fighter?"
In One Piece lore, only one in a million people are born with the Color of the Supreme King. But using it is not enough. As Kaido explains in Episode 1028, only a handful of the strongest can coat themselves in it.
This ability allows the user to bypass traditional durability. Luffy could not hurt Kaido with Armament Haki (Episode 914-1015). But the moment he uses Advanced Supreme Haki in Episode 1028, he finally fights Kaido on equal footing.
