Mark Albert is a fictional character played by James LeGros who appeared in the third and fourth seasons of the Fox Television show Ally McBeal.
In his introductory episode, Ally viewed Mark as a threat to her own position at Cage & Fish and as an undesirable replacement for her recently deceased friend long-term lover Billy.
Introduced as a new associate for the law firm of Cage & Fish, Mark was initially portrayed as both highly skilled in criminal law, nicknamed "the Closer" for his unparalleled skill with closing arguments and highly eccentric character such as obsessed with dental hygiene.
After the romantic storylines with both Cindy and Elaine were resolved, Mark's character was quickly and quietly phased out at the end of season four.
The character's absence was never explained—a recurring characteristic of shows run by David E. Kelley, see also articles on Ally McBeal, Boston Public, and The Practice.
