Doyle, 69, of Shepherdstown, was noncommital about his plans other than to say he had other interests he wanted to pursue "while I still have the energy."
He said whatever he gets involved in it will have something to do with the issues that he favored while in the House — tax reform, land use, education and civil liberties. He would not say if a new career would involve lobbying.
Doyle, D-57th, is one of only two Democrats in the three-county Eastern Panhandle delegation. He said the lack of Democratic representation in the party's caucus in the House hurts the region.
Statewide, Democrats enjoy a ratio of 65-35 over Republicans in the House of Delegates, he said.
Doyle lost his first two bids in primary races for the House in 1978 and 1980. He won his first seat in 1982 and lost in 1984 to Del. John Overington. The district's boundaries have changed since then.
He has held his seat for 19 consecutive years since 1992.
Doyle beat Republican Elliott Simon from Harpers Ferry in the 2010 election. Simon has already announced that he plans to run again next year, but this time he will face a different Democratic opponent.
