Expert Difficulty is one of the track difficulties the player can challenge in the Bloons Tower Defense Games. Expert Difficulty is the second hardest difficulty, with Extreme Difficulty being the hardest. This difficulty was introduced in Bloons TD 4 and it is also the highest track difficulty in Bloons TD 4 and Bloons TD 4 Expansion. In Bloons TD 5, it is the second hardest difficulty, because of Extreme Difficulty being added. These tracks usually have to be unlocked by reaching a certain Rank (28 for Clock, 34 for Castle, 40 for Death Valley, 41 for Drag Strip, 43 for Tree Tops).

This difficulty tends to be easier than the Extreme Difficulty (through to some, Expert Tracks are harder than them.), however these tracks are still quite hard to complete on Medium Difficulty or harder.
