The women's 4 × 100 metres relay event at the 1990 Commonwealth Games was held on 3 February at the Mount Smart Stadium in Auckland.
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. A relay baton is carried by each runner. Prior to 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017 that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, the incoming runner cannot touch the baton after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colors and style are only "recommended". While most legacy tracks will still have the older markings, the rule change still uses existing marks. Not all governing body jurisdictions have adopted the rule change.
At the 1990 Commonwealth Games, the athletics events were held at the Mount Smart Stadium in Auckland, New Zealand from 27 January to 3 February 1990. A total of 42 events were contested, 23 by male and 19 by female athletes.
