Joseph Donald Walsh Jr. (born March 1, 1941) is a front office adviser of the Indiana Pacers and a former professional basketball coach.

Walsh was recruited to play college basketball at the University of North Carolina for then head coach Frank McGuire.

He later took a position as general manager with the Pacers, where in 1987 he made the then-controversial decision to select Reggie Miller in the NBA Draft over local hero Steve Alford of Indiana University.

During his time as the president and CEO, he oversaw all operations of the Pacers Foundation, Indiana Fever (WNBA), and Conseco Fieldhouse.

Then, he traded Mardy Collins and Zach Randolph for Cuttino Mobley and Tim Thomas of the Los Angeles Clippers.

[3] Though Mobley retired of a heart condition, his contract, as well as those of Harrington and Thomas, expired at the end of the 2009–2010 NBA season, decreasing the Knicks' payroll by $27 million and giving them enough cap space to sign anyone notable from the heralded free agent class of 2010 which included NBA players such as LeBron James, Dwyane Wade, Chris Bosh, Amar'e Stoudemire, and Joe Johnson.
