Mouth Silence is the second mashup mixtape by American musician and comedian Neil Cicierega.

Following the format of his previous release, Mouth Sounds, the mixtape is composed of mashups and remixes of popular songs from the 1980s, 1990s and 2000s.

Club describing it as "laugh out loud horrifying"[5] and Ryan Manning of The Verge promising that listeners would "have a strong reaction, negative, positive, horrified, glorified".
