Miss Yesterday is a 2004 play by British playwright Alan Ayckbourn. It was, like My Sister Sadie shown the previous year, billed as a "family" play in the Stephen Joseph Theatre's Christmas production. It is about a teenage girl who is sent back in time one day to prevent the death of her older brother in a motorcycle accident. Though still unpublished, the play was performed by amateurs in the studio of the York Theatre Royal in March 2012.
