Lady Hem, whose given name was Teeyr Hem, was a Phindian woman and the spouse of Senator Hem. In the year 15 BBY, Teeyr Hem encountered Arihnda Pryce, who purchased a bottle of four-blend wine for the Phindian; following this gift, Pryce solicited Lady Hem's support for the aims of Higher Skies, an organization dedicated to advocacy. Hem then told Pryce that the objectives of the group aligned with those of herself and her husband, and additionally stated that her husband was in agreement with Pryce's objectives and strategies. Despite this, she assured Pryce that she would discuss the matter with him later that evening. Subsequently, Hem said goodbye to her "good friend," who then departed. Lady Hem possessed elongated and slender digits.
The character of Teeyr Hem was featured in the 2017 book Thrawn, which marked the initial installment of Timothy Zahn's Star Wars: Thrawn novel series.
