Walden Thoreau Schmidt is a fictional character in the CBS sitcom Two and a Half Men, portrayed by Ashton Kutcher. The character was introduced in the season nine premiere episode, "Nice to Meet You, Walden Schmidt" to replace the character of Charlie Harper after actor Charlie Sheen was sacked from the series. Walden was a main character throughout the show's final four seasons (seasons 9-12). He is listed on Forbes' fictional list of the top 15 richest characters as number 11, with a wealth of approximately $1.3 billion.

Schmidt is introduced to the series as a billionaire internet entrepreneur who has recently been divorced and is now suicidal. After unsuccessfully attempting suicide, he turns up at Charlie Harper's beach house and decides to buy it from Charlie's brother, Alan, to whom Charlie has left the house in his will, after dying in France.

Over the course of his duration on the series, Walden's personality greatly matured.

For the first eight seasons of Two and a Half Men, the series' main character was Charlie Harper, portrayed by actor Charlie Sheen. In February 2011, after continued verbal attacks against series creator Chuck Lorre by Sheen, CBS announced that Two and a Half Men would suspend production for the rest of its eighth season. On March 7, CBS and Warner Bros. Television jointly announced that Sheen had been sacked from Two and a Half Men, citing "moral turpitude" as a main cause of separation.

In April 2011, Chuck Lorre announced that he had developed an idea for a Two and a Half Men reboot that would exclude Sheen and have Jon Cryer, who portrayed Alan Harper, in a lead role alongside a new character. On May 13, CBS announced that Ashton Kutcher would join the cast. Kutcher was quoted as saying, "I can't replace Charlie Sheen but I'm going to work my ass off to entertain the hell out of people!"
