Officially merged into the UFC from the WEC in 2010, the 145-pound division has quietly become one of the most historically rich weight classes in MMA.

Long title reigns. Brief explosions. Technical excellence.
And a rotating cast of legends like Frankie Edgar, The Korean Zombie, Urijah Faber, Dustin Poirier, Cub Swanson, Max Holloway, etc. shaping its identity.

Here’s a complete look at every UFC featherweight champion, and what defined their reign.

---

👑 Jose Aldo (2010–2015)

When the UFC absorbed the WEC, Jose Aldo also arrived as the standard.
Already the reigning WEC featherweight king, Aldo was promoted as the UFC’s inaugural 145-lb champion and proceeded to dominate the division for five years.

Title defenses:

• Mark Hominick (UFC 129)
• Kenny Florian (UFC 136)
• Chad Mendes (UFC 142)
• Frankie Edgar (UFC 156)
• Chan Sung Jung (UFC 163)
• Ricardo Lamas (UFC 169)
• Chad Mendes (UFC 179)

Aldo’s reign combined:

• Defensive genius
• Devastating leg kicks
• Championship composure

Undefeated for nearly a decade, he set a benchmark that defined greatness at featherweight.

🍀 Conor McGregor (2015–2016)

Conor McGregor’s reign was short, loud, and historically disruptive.
After winning the interim title against Chad Mendes, McGregor knocked out Aldo in 13 seconds at UFC 194, one of the most shocking finishes in MMA history.

And that was it.
McGregor never defended the belt, vacating it after moving up to lightweight and chasing double-champion status.

Impact-wise, he changed the sport.
Legacy-wise at 145, it remains the shortest and least defended reign in divisional history.

---

👑 Jose Aldo (2016–2017)

Aldo reclaimed gold by defeating Frankie Edgar for the interim title at UFC 200. When McGregor vacated, Aldo was promoted to undisputed champion once again.
This second reign lacked longevity, but it reinforced Aldo’s resilience and relevance in a division he helped build.

---

🪽 Max Holloway (2017–2019)

Max Holloway represented a new “Bless” era.
After winning the interim title against Anthony Pettis, Holloway stopped Jose Aldo at UFC 212 to claim the undisputed belt, then did it again in their rematch.

Title defenses:

• Jose Aldo (UFC 218)
• Brian Ortega (UFC 231)
• Frankie Edgar (UFC 240)

Holloway proved something radical at the time:
Volume, pace, and durability could overwhelm power and precision.

His reign redefined striking attrition and established him as one of the most beloved champions in UFC history.

🎖️ Alexander Volkanovski (2019–2024)

Volkanovski dethroned Holloway at UFC 245 and ushered in the most strategically refined reign the division has ever seen.

Title defenses:

• Max Holloway (UFC 251)
• Brian Ortega (UFC 266)
• Chan Sung Jung (UFC 273)
• Max Holloway (UFC 276)
• Yair Rodriguez (UFC 290)

Volkanovski’s greatness came from:

• Tactical discipline
• Defensive awareness
• Game-specific preparation

He also challenged for lightweight gold against Islam Makhachev, falling short but enhancing his reputation across weight classes.

---

🐈‍⬛ Yair Rodriguez (Interim, 2023)

While Volkanovski pursued lightweight ambitions, Yair Rodriguez captured the interim title by submitting Josh Emmett.
Dynamic, unpredictable, and dangerous, Yair’s reign was transitional rather than definitive, ending when Volkanovski reclaimed undisputed status.

---

🐂 Ilia Topuria (2024–2025)

El Matador delivered the division’s next shockwave.
He knocked out Volkanovski at UFC 298 to become champion, then defended the belt against Max Holloway at UFC 308 also by knocked out.
Two legends, two got KOed, myth unlocked.

After just one defense, Topuria vacated the title to pursue lightweight gold, echoing the McGregor path.
Young. Explosive. Brief. Unfinished.

---

🎖️ Alexander Volkanovski (2025–Present)

Volkanovski reclaimed the featherweight throne by defeating Diego Lopes, then defended it in their rematch at UFC 325.

With this run:
He tied Jose Aldo for most successful title defenses
Cemented his place in the featherweight GOAT debate

At this point, the question isn’t if Volkanovski surpasses Aldo.
It’s how far he pushes the record.

🧠 The Featherweight Legacy

The 145-lb division tells a unique story:

Aldo built it
McGregor disrupted it
Holloway expanded it
Topuria disrupted it again
Volkanovski refined it

There’re only five undisputed champions in featherweight since the beginning til now.
And the next chapter is still being written.
