Shakespeare's Sonnet 33 is one of 154 sonnets written by the English playwright and poet William Shakespeare. It is a member of the Fair Youth sequence, in which the poet expresses his love towards a young man. This sonnet is the first of what are sometimes called the estrangement sonnets, numbers 33–36: poems concerned with the speaker's response to an unspecified "sensual fault" mentioned in (35) committed by his beloved.

William Shakespeare's Sonnet 35 is part of the Fair Youth sequence, commonly agreed to be addressed to a young man; more narrowly, it is part of a sequence running from 33 to 42, in which the speaker considers a sin committed against him by the young man, which the speaker struggles to forgive.
