Dyllan Christopher (born 12 December 1991) is an American actor. He played in one of five major roles in the 2006 movie Unaccompanied Minors as Spencer, the leader of a group of kids who get stuck in an airport on Christmas. He worked alongside Quinn Shepard and Tyler James Williams. He acted in Disney Channel's ID Address as Peter. He is in the Hallmark Singing Christmas Card commercials shown in December 2006.

Dyllan started his successful television/commercial career staring in a Lemon Clorox commercial at the age of 2, and was immediately hired to play "Avery Brown," Candice Bergen's son, on "Murphy Brown." He played "young Dudley" in "Dudley Do-Right" with Brendan Fraser; Will Patton's son in "Armageddon," and John Travolta's son in "Mad City." Dyllan went on to be cast as the lead child character "Ralphy," Tim Daly's haunted son, in the Stephen King ABC mini-series "Storm of the Century" shot entirely in Toronto, Canada. He later became a series regular on Showtime's "Out of Order" opposite Eric Stoltz, Felicity Huffman, and William H. Macy. Dyllan has tackled some very intense parts such as portraying an autistic child on "Without a Trace." He actually attended a class of autistic children and interacted with them so he could get into the mind of his character. Starring as Spencer in Unaccompanied Minors, a Warner Brothers holiday movie, also challenged him with a 6 day work week.
