Samaki Ijuma Walker (born February 25, 1976) is an American retired professional basketball power forward and center.

Walker continued to play for the NBA with the San Antonio Spurs (1999–2001), Los Angeles Lakers (2001–2003), Miami Heat (2003–2004), Washington Wizards (2004–2005), and Indiana Pacers (2005–2006).

Selected ninth overall by the Dallas Mavericks, Walker drew widespread attention on draft day for wearing an all-white suit with a matching fedora.

[7] That season, new coach Don Nelson began drastically changing the makeup of the team, and Walker was actually the longest-tenured Maverick while still a rookie.

In the summer of 2001, Walker signed as a free agent with the two-time defending champion Los Angeles Lakers, who needed a power forward following the departure of veteran Horace Grant.

Shaq has credited Walker for his contributions to the Lakers championship run, namely his play against Chris Webber of the Kings during the Western Conference Finals series.

He became a free agent after the season, and the Lakers opted to sign Karl Malone and draft Brian Cook, effectively ending his run in Los Angeles.

Walker spent a brief seven–game stint with the Indiana Pacers[18] during the 2005–06 season and a portion of the 2007 offseason with the Milwaukee Bucks,[19] but was unable to latch on with either team.

[26] After his 17-year-old nephew Deandre Hillman died from cardiac arrest in 2001, Walker joined the non-profit organization Start-A-Heart, which provides automated external defibrillators to schools and other public facilities.

[27] He spent the 2006–07 season forming Life Choices Foundation, a nonprofit aiming to keep youth in inner-city Los Angeles out of trouble.
