Cristobal Arreola (born March 5, 1981) is an American former professional boxer who challenged three times for the WBC heavyweight title.

In 2001 at 20 he got back into boxing and after only three months of training managed to win the National Golden Gloves at the Light Heavyweight division.

[3] After another hiatus from boxing, this time for two years, he tried to come back for the 2003 Golden Gloves but arrived shortly after the check-in deadline prompting him to turn pro.

"[5] In 2005, he fought Domonic Jenkins who despite his record of only 6–3 held a win over Malcolm Tann (and later KOd amateur stars Victor Bisbal and Carlos Barnett).

[6] Arreola defeated the previously retired heavyweight veteran Jameel McCline (40-8 23 KO's) on April 11, 2009, with a knockout at 2:01 of the 4th round.

After his win, Arreola was the number one contender to challenge Vitali Klitschko for his WBC Heavyweight title belt.

Arreola's corner and the referee stopped the fight before the start of the 11th round, giving Klitschko a 10th-round RTD (TKO) victory.

[9] Soon after his first career loss, Arreola fought Brian Minto as an undercard for the Paul Williams vs. Sergio Martínez fight.

[10] Arreola lost his next fight, to former two-division world champion Tomasz Adamek, by majority decision on 24 April 2010.

[12] After his knockout over American Joey Abell on ESPN,[13] Arreola took out title contender Nagy Aguilera in the third round.

[14] Thirteen days after the fight with Aguilera, Cristobal knocked out tough veteran Kendrick Releford in the seventh round, as the main-event on ESPN.

Arreola's next fight was on the Paul Williams vs. Nobuhiro Ishida undercard at the American Bank Center, Corpus Christi, Texas, on February 18, 2012.

The fight took place during the first Premier Boxing Champions on Spike TV broadcast at the Citizens Business Bank Arena in Ontario, CA.

[24] After two consecutive wins following his loss to Deontay Wilder, Arreola faced the unbeaten Adam Kownacki in a thrilling fight on August 3, 2019.

The two men put on a record-breaking heavyweight display at the Barclays Center, New York, combining to throw over 2100 punches over 12 rounds.

[25] Following Arreola's loss to Adam Kownacki, he next returned to the ring over a year later on May 1, 2021 to face former unified heavyweight champion Andy Ruiz Jr. on Fox PPV.
