Grace Marguerite, Lady Hay Drummond-Hay (née Lethbridge, 12 September 1895 – 12 February 1946) was a British journalist, who was the first woman to travel around the world by air (in a zeppelin).

[1] Grace Lethbridge was married in 1920 to Sir Robert Hay Drummond-Hay (1846–1925) at the age of 25, her husband being nearly fifty years older.

This airship, the LZ 127 Graf Zeppelin, was also the first to circumnavigate the world, in August 1929, taking off at Lakehurst, New Jersey and arriving there again 21 days later, after stops in Friedrichshafen, Germany, Tokyo, and Los Angeles.

Among her 19 companion travellers were: Drummond-Hay gained fame after she arrived in New York, and her career as a journalist was secured for the next decade.

During World War II, Lady Drummond-Hay and von Wiegand were interned in a Japanese camp in the Philippines.

[5] At her funeral service, many people paid their last respects, including William Randolph Hearst and Marion Davies.

Her name is mentioned in several books on the history of zeppelin flights, but no major biography or other significant document has been written about her life.

The narration consisted mainly of readings from Lady Drummond-Hay's articles and journal, and included discussion of her relationship with von Wiegand.
