Ellis Yarnal Berry (October 6, 1902 – April 1, 1999) was an American attorney, newspaper publisher and politician, elected to the United States House of Representatives from South Dakota.

Berry started his law practice in Kennebec, South Dakota; two years later, he moved to McLaughlin.

He was elected as state's attorney, probate court judge for Corson County, and mayor of McLaughlin.

In 1950, Berry was elected as a Republican to the United States House of Representatives, and reelected nine consecutive times, retiring in 1971.

In 1966, journalist Drew Pearson reported that Berry was one of a group of four Congressmen who had received the "Statesman of the Republic" award from Liberty Lobby for their "right-wing activities".
