The name of Hamlet's mother in William Shakespeare's play is Gertrude.

Gertrude's Role as Queen of Denmark

Gertrude is the Queen of Denmark who marries Claudius, her late husband's brother, shortly after King Hamlet's death. This hasty remarriage becomes a major source of turmoil for her son, Prince Hamlet, who resents her quick transition from mourning to a new marriage. The relationship between mother and son is turbulent throughout the play, as Hamlet struggles with what he perceives as her betrayal of his father's memory.

Her Character in the Play

Gertrude is introduced in Act 1, Scene 2, where she attempts to comfort Hamlet over the loss of his father and urges him to stay at home rather than return to school in Wittenberg. While she deeply loves her son, Shakespeare portrays her as a complex character—described as a shallow, weak woman who seeks affection and status more urgently than moral rectitude or truth. Throughout the play, she appears unaware of the depth of corruption surrounding her, revealing no guilt about her marriage to Claudius despite the suspicious circumstances of her first husband's death.

Her concern for Hamlet continues into the second act, where she sides with King Claudius in sending Rosencrantz and Guildenstern to cheer up her melancholy son. Ultimately, Gertrude's fate is tragic—she dies after drinking poisoned wine that was intended for Hamlet.

TLDR: Hamlet's mother is named Gertrude , Queen of Denmark, whose remarriage to Claudius after King Hamlet's death drives much of the play's conflict. Information gathered from public forums or data available on the internet and portrayed here.
