Sad Sappy Sucker (or by the full title on its cover art Sad Sappy Sucker Chokin on a Mouthful of Lost Thoughts[8][9]) is a 2001 compilation album released by alternative rock band Modest Mouse.

Several songs were recorded at Olympia, Washington's Dub Narcotic Studios by Beat Happening frontman Calvin Johnson.

[10] PopMatters said that "taken on its own merits, Sad Sappy Sucker is pretty good, but the out-and-out strangeness of it all and the fact that it doesn’t hold together as a real album may throw off the uninitiated (and who can blame them?).

"[5] Stereogum declared it the worst Modest Mouse album, stating "the album is as grating and undercooked as indie rock debuts come, full of indulgent studio experiments, half-assed sketches, and tunes that sound like a generic sadcore band's demo cassette in high-speed dub mode....Sad Sappy Sucker asks the question: 'How many Built To Spills do we need?

Tracks 16–24 come from Isaac Brock's answering machine — he originally had a "Call to Dial a Song" service, similar to They Might Be Giants' Dial-A-Song.
