Lady Margaret Hall Boat Club (LMHBC) is a rowing club for members and staff of Lady Margaret Hall (LMH), Oxford.

It was founded by 1899 although it was not able to compete in intercollegiate racing until 1976, when a women’s division was finally established. As the senior women’s college, LMH were placed at 1st on the river for the inaugural women’s bumps races and obtained Headship in 1977.

The first men’s crew was established in 1980 following the admission of male students into the previously all-women’s college.

LMHBC first competed in inter-college OURCs racing events in 1977, when a women's division was finally established (LMH was a women-only college for the first 100 years of its foundation). As the senior women's college LMH was placed first on the river for the inaugural women's division. The club has provided rowers for the Boat Race, the Women's Boat Race, and the Isis Reserves Race.

A former president, Monica Fisher (née Pring-Mill) was responsible for instigating some of the biggest changes in Women's Boat Race history, which raised the regularity and status of that event.

For a period around 2010 three times World Lightweight Sculling Champion Peter Moir Haining coached LMHBC.

The club is affiliated to British Rowing.
