James B. Lynch (died 12 March 1954) was an Irish Fianna Fáil politician, who served for 16 years as a Teachta Dála (TD) before being elected as a Senator for three years.^[1]

A physician and surgeon before entering politics, Lynch was elected to Dáil Éireann on his first attempt, at the 1932 general election, when he stood as a Fianna Fáil candidate in the 7-seat Dublin South constituency. He was the last candidate to be elected, and took his seat in the 7th Dáil.^[2]

He was returned at the 1933 general election, but did not contest the 1937 general election. He stood again at the 1938 general election and was re-elected. He retained his seat at the next two general elections, but when constituency boundaries were revised at the 1948 general election, he stood in the neighbouring Dublin South-Central but was not elected. He stood again in Dublin South-Central at the 1951 general election, but lost again.

He then stood at the 1951 election to Seanad Éireann, winning won a seat on the Cultural and Educational Panel in the 7th Seanad, where he served until his death in March 1954. His widow Celia Lynch was a TD for Dublin South-Central from 1954 to 1977.
