Under Construction, Part II is the third and final studio album released by hip hop duo Timbaland & Magoo.

Many other guest stars, from Brandy to Sebastian, Bubba Sparxxx, Wyclef Jean and Beenie Man, also appear on the album.

AllMusic editor John Bush found that "there aren't quite enough guest features or catchy hooks to make this a must-purchase for most rap fans, but Timbaland always has a few tricks up his sleeve."

He remarked that "aside from Missy and Bubba Sparxxx, Timba's actually the best rapper on display, much improved from his previous solo shots or his infrequent rhymes on other artists' records.

"[7] In a negative review, Rolling Stone's Jon Caramanica called Under Construction, Part II the "duo's third and weakest collaborative album."
