Cody Allen Zeller (born October 5, 1992) is an American professional basketball player who last played for the New Orleans Pelicans of the National Basketball Association (NBA). He played high school basketball at Washington High School in Washington, Indiana, where he was named Indiana Mr. Basketball as a senior in 2011.

Zeller played two seasons of college basketball for the Indiana Hoosiers from 2011 to 2013. During his freshman season, he was named Big Ten Freshman of the Year and part of the All-Big Ten second team. In his sophomore season, he was named as a second-team All-American and part of the All-Big Ten first team.

Zeller was selected fourth overall in the 2013 NBA draft by the Charlotte Bobcats, who rebranded to the Hornets a year later. As a rookie, he was named to the NBA All-Rookie Second Team. Following eight seasons with the Hornets, he signed with the Portland Trail Blazers in August 2021, whom he spent one season with. Zeller joined the Miami Heat in February 2023, with whom he reached the 2023 NBA Finals. He then signed with the New Orleans Pelicans in July 2023.

Following the end of his senior season, Zeller was named Indiana Mr. Basketball, the state's highest honor for high school players and an award both of his elder brothers also won. Zeller became the 26th Mr. Basketball from the state of Indiana to play for the Hoosiers. Other honors Zeller won in his high school career include first-team All-State honors from the Indiana Basketball Coaches Association, the Gatorade Player of the Year accolades in Indiana, and a second-team Parade All-American. According to ESPN Zeller was the 13th best overall recruit in 2011. Scout.com had him rated 12th nationally and third at his position, while Rivals.com had him slotted 15th in the country and fourth at his position.

On November 12, 2010, Zeller committed to play for Indiana University, turning down offers from North Carolina and Butler. Upon his commitment he was labeled "the savior of Indiana basketball." Zeller was nicknamed "The Big Handsome" during his time at IU.

In Zeller's first year as a Hoosier during the 2011–12 season he led the team with 15.6 points and 6.6 rebounds per game while shooting 62.3 percent (200-of-321) from the field and 75.5 percent (163-of-216) from the free-throw line. He ranked fourth in the country in field goal percentage, led the Big Ten Conference and posted the second-highest percentage in school history. His offensive rating of 126.8 ranked him 14th nationwide. Zeller was the Big Ten's Freshman of the Year, as voted on by the coaches, after earning Big Ten Freshman of the Week seven times. He was also Second Team All-Big Ten and a First Team Freshman All-American. He was a finalist for the Wayman Tisdale Award (USBWA National Freshman of the Year) and was a candidate for the John Wooden Award and Oscar Robertson Trophy.

Although projected to be a top ten pick in the 2012 NBA draft, Zeller decided to return for his sophomore season at Indiana, along with teammate Christian Watford. In a statement issued by the Indiana Athletic Department, he said, "I grew up hoping that one day I would get the opportunity to play in the NBA, but at this point, I'm not ready for my college experience to be over...My college experience at IU this year has exceeded my expectations, on and off the court."

Due in part to Zeller's leadership, the Indiana Hoosiers finished the 2012–13 season as the outright Big Ten champions. He finished the regular season as the conference's third-highest scorer (16.8 points) and second highest rebounder (8.2), along with second in the league in shooting at 57% while only trailing teammate Victor Oladipo in the Big Ten.
