Lady Aya (綾御前, Aya-Gozen, 1524 – March 10, 1609) was a Japanese noblewoman from the Sengoku period.

Aya is best known for her role in events before and after the siege of Otate; she lamented the Uesugi civil war for succession after Kenshin's death and refused to support either heir.

According to legend, she was a highly intelligent woman and skilled in recognizing talent, being responsible for employing various samurai to work for Kenshin.

Later, Sentōin received protection from Kagekatsu and accompanied him during transfers to Aizu in 1598 and to Yonezawa in 1601.

The actual characters to write her name are confirmed from the death register kept at the temple.
